How to invert colors horizontally halfway through a word using CSS [duplicate]

What I am looking for:

A way to style one HALF of a character. (In this case, half the letter being transparent)

What I have currently searched for and tried (With no luck):

  • Methods for styling half of a character/letter
  • Styling part of a character with CSS or JavaScript
  • Apply CSS to 50% of a character

Below is an example of what I am trying to obtain.

x

Does a CSS or JavaScript solution exist for this, or am I going to have to resort to images? I would prefer not to go the image route as this text will end up being generated dynamically.


UPDATE:

Since many have asked why I would ever want to style half of a character, this is why. My city had recently spent $250,000 to define a new "brand" for itself. This logo is what they came up with. Many people have complained about the simplicity and lack of creativity and continue to do so. My goal was to come up with this website as a joke. Type in 'Halifax' and you will see what I mean.

  • Pure CSS for a Single Character
  • JavaScript used for automation across text or multiple characters
  • Preserves Text Accessibility for screen readers for the blind or visually impaired

Part 1: Basic Solution

Half Style on text

Demo: http://jsfiddle.net/arbel/pd9yB/1694/


This works on any dynamic text, or a single character, and is all automated. All you need to do is add a class on the target text and the rest is taken care of.

Also, the accessibility of the original text is preserved for screen readers for the blind or visually impaired.

Explanation for a single character:

Pure CSS. All you need to do is to apply .halfStyle class to each element that contains the character you want to be half-styled.

For each span element containing the character, you can create a data attribute, for example here data-content="X", and on the pseudo element use content: attr(data-content); so the .halfStyle:before class will be dynamic and you won't need to hard code it for every instance.

Explanation for any text:

Simply add textToHalfStyle class to the element containing the text.


// jQuery for automated mode
jQuery(function($) {
    var text, chars, $el, i, output;

    // Iterate over all class occurences
    $('.textToHalfStyle').each(function(idx, el) {
    $el = $(el);
    text = $el.text();
    chars = text.split('');

    // Set the screen-reader text
    $el.html('<span style="position: absolute !important;clip: rect(1px 1px 1px 1px);clip: rect(1px, 1px, 1px, 1px);">' + text + '</span>');

    // Reset output for appending
    output = '';

    // Iterate over all chars in the text
    for (i = 0; i < chars.length; i++) {
        // Create a styled element for each character and append to container
        output += '<span aria-hidden="true" class="halfStyle" data-content="' + chars[i] + '">' + chars[i] + '</span>';
    }

    // Write to DOM only once
    $el.append(output);
  });
});
.halfStyle {
    position: relative;
    display: inline-block;
    font-size: 80px; /* or any font size will work */
    color: black; /* or transparent, any color */
    overflow: hidden;
    white-space: pre; /* to preserve the spaces from collapsing */
}

.halfStyle:before {
    display: block;
    z-index: 1;
    position: absolute;
    top: 0;
    left: 0;
    width: 50%;
    content: attr(data-content); /* dynamic content for the pseudo element */
    overflow: hidden;
    color: #f00;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

Part 2: Advanced solution - Independent left and right parts

Half Style on text - advanced - With Text Shadow

With this solution you can style left and right parts, individually and independently.

Everything is the same, only more advanced CSS does the magic.

jQuery(function($) {
    var text, chars, $el, i, output;

    // Iterate over all class occurences
    $('.textToHalfStyle').each(function(idx, el) {
        $el = $(el);
        text = $el.text();
        chars = text.split('');

        // Set the screen-reader text
        $el.html('<span style="position: absolute !important;clip: rect(1px 1px 1px 1px);clip: rect(1px, 1px, 1px, 1px);">' + text + '</span>');

        // Reset output for appending
        output = '';

        // Iterate over all chars in the text
        for (i = 0; i < chars.length; i++) {
            // Create a styled element for each character and append to container
            output += '<span aria-hidden="true" class="halfStyle" data-content="' + chars[i] + '">' + chars[i] + '</span>';
        }

        // Write to DOM only once
        $el.append(output);
    });
});
.halfStyle {
    position: relative;
    display: inline-block;
    font-size: 80px; /* or any font size will work */
    color: transparent; /* hide the base character */
    overflow: hidden;
    white-space: pre; /* to preserve the spaces from collapsing */
}

.halfStyle:before { /* creates the left part */
    display: block;
    z-index: 1;
    position: absolute;
    top: 0;
    width: 50%;
    content: attr(data-content); /* dynamic content for the pseudo element */
    overflow: hidden;
    pointer-events: none; /* so the base char is selectable by mouse */
    color: #f00; /* for demo purposes */
    text-shadow: 2px -2px 0px #af0; /* for demo purposes */
}

.halfStyle:after { /* creates the right part */
    display: block;

Part 4: Ready for Production

Customized different Half-Style style-sets can be used on desired elements on the same page. You can define multiple style-sets and tell the plugin which one to use.

The plugin uses data attribute data-halfstyle="[-CustomClassName-]" on the target .textToHalfStyle elements and makes all the necessary changes automatically.

So, simply on the element containing the text add textToHalfStyle class and data attribute data-halfstyle="[-CustomClassName-]". The plugin will do the rest of the job.

halfStyle - Multiple on Same Page

Also the CSS style-sets' class definitions match the [-CustomClassName-] part mentioned above and is chained to .halfStyle, so we will have .halfStyle.[-CustomClassName-]

I've just finished developing the plugin and it is available for everyone to use! Hope you will enjoy it.

View Project on GitHub - View Project Website. (so you can see all the split styles)

Usage

First of all, make sure you have the jQuery library is included. The best way to get the latest jQuery version is to update your head tag with:

<script src="http://code.jquery.com/jquery-latest.min.js"></script>

After downloading the files, make sure you include them in your project:

<link rel="stylesheet" type="text/css" href="css/splitchar.css">
<script type="text/javascript" src="js/splitchar.js"></script>

Markup

All you have to do is to asign the class splitchar , followed by the desired style to the element wrapping your text. e.g

<h1 class="splitchar horizontal">Splitchar</h1>

After all this is done, just make sure you call the jQuery function in your document ready file like this:

$(".splitchar").splitchar();

Customizing

In order to make the text look exactly as you want it to, all you have to do is apply your design like this:

.horizontal { /* Base CSS - e.g font-size */ }
.horizontal:before { /* CSS for the left half */ }
.horizontal:after { /* CSS for the right half */ }


That's it! Now you have the Splitchar plugin all set. More info about it at http://razvanbalosin.com/Splitchar.js/.

Yes, you can do this with only one character and only CSS:

http://jsbin.com/rexoyice/1/

h1 {
  display: inline-block;
  margin: 0; /* for demo snippet */
  line-height: 1em; /* for demo snippet */
  font-family: helvetica, arial, sans-serif;
  font-weight: bold;
  font-size: 300px;
  background: linear-gradient(to right, #7db9e8 50%,#1e5799 50%);
  background-clip: text;
  -webkit-text-fill-color: transparent;
}
<h1>X</h1>

Visually, all the examples that use two characters (be it via JS, CSS pseudo elements, or just HTML) look fine, but note that that all adds content to the DOM which may cause accessibility--as well as text selection/cut/paste issues.

Example


JSFiddle DEMO

We'll do it using just CSS pseudo selectors!

This technique will work with dynamically generated content and different font sizes and widths.

HTML:

<div class='split-color'>Two is better than one.</div>

CSS:

.split-color > span {
    white-space: pre-line;
    position: relative;
    color: #409FBF;
}

.split-color > span:before {
    content: attr(data-content);
    pointer-events: none;  /* Prevents events from targeting pseudo-element */
    position: absolute;
    overflow: hidden;
    color: #264A73;
    width: 50%;
    z-index: 1;
}

To wrap the dynamically generated string, you could use a function like this:

// Wrap each letter in a span tag and return an HTML string
// that can be used to replace the original text
function wrapString(str) {
  var output = [];
  str.split('').forEach(function(letter) {
    var wrapper = document.createElement('span');
    wrapper.dataset.content = wrapper.innerHTML = letter;

    output.push(wrapper.outerHTML);
  });

  return output.join('');
}

// Replace the original text with the split-color text
window.onload = function() {
    var el  = document.querySelector('.split-color'),
        txt = el.innerHTML;
    
    el.innerHTML = wrapString(txt);
}

Here an ugly implementation in canvas. I tried this solution, but the results are worse than I expected, so here it is anyway.

Canvas example

$("div").each(function() {
  var CHARS = $(this).text().split('');
  $(this).html("");
  $.each(CHARS, function(index, char) {
    var canvas = $("<canvas />")
      .css("width", "40px")
      .css("height", "40px")
      .get(0);
    $("div").append(canvas);
    var ctx = canvas.getContext("2d");
    var gradient = ctx.createLinearGradient(0, 0, 130, 0);
    gradient.addColorStop("0", "blue");
    gradient.addColorStop("0.5", "blue");
    gradient.addColorStop("0.51", "red");
    gradient.addColorStop("1.0", "red");
    ctx.font = '130pt Calibri';
    ctx.fillStyle = gradient;
    ctx.fillText(char, 10, 130);
  });
});

Closest I can get:

$(function(){
  $('span').width($('span').width()/2);
  $('span:nth-child(2)').css('text-indent', -$('span').width());
});
body{
  font-family: arial;
}
span{
  display: inline-block;
  overflow: hidden;
}
span:nth-child(2){
  color: red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<span>X</span><span>X</span>

Demo: http://jsfiddle.net/9wxfY/2/

Heres a version that just uses one span: http://jsfiddle.net/9wxfY/4/

Another CSS-only solution (though data-attribute is needed if you don't want to write letter-specific CSS). This one works more across the board (Tested IE 9/10, Chrome latest & FF latest)

span {
  position: relative;
  color: rgba(50,50,200,0.5);
}

span:before {
  content: attr(data-char);
  position: absolute;
  width: 50%;
  overflow: hidden;
  color: rgb(50,50,200);
}
<span data-char="X">X</span>

Limited CSS and jQuery Solution

I am not sure how elegant this solution is, but it cuts everything exactly in half: http://jsfiddle.net/9wxfY/11/

Otherwise, I have created a nice solution for you... All you need to do is have this for your HTML:

Take a look at this most recent, and accurate, edit as of 6/13/2016 : http://jsfiddle.net/9wxfY/43/

As for the CSS, it is very limited... You only need to apply it to :nth-child(even)

$(function(){
  var $hc = $('.half-color');
  var str = $hc.text();
  $hc.html("");

  var i = 0;
  var chars;
  var dupText;

  while(i < str.length){
    chars = str[i];
    if(chars == " ") chars = "&nbsp;";
    dupText = "<span>" + chars + "</span>";

    var firstHalf = $(dupText);
    var secondHalf = $(dupText);

    $hc.append(firstHalf)
    $hc.append(secondHalf)

    var width = firstHalf.width()/2;

    firstHalf.width(width);
    secondHalf.css('text-indent', -width);

    i++;
  }
});
.half-color span{
  font-size: 2em;
  display: inline-block;
  overflow: hidden;
}
.half-color span:nth-child(even){
  color: red;
}

<div class="half-color">This is a sentence</div>

How about something like this for shorter text?

It could even work for longer text if you did something with a loop, repeating the characters with JavaScript. Anyway, the result is something like this:

Is it possible to apply CSS to half of a character?

p.char {
  position: relative;
  display: inline-block;
  font-size: 60px;
  color: red;
}

p.char:before {
  position: absolute;
  content: attr(char);
  width: 50%;
  overflow: hidden;
  color: black;
}
<p class="char" char="S">S</p>
<p class="char" char="t">t</p>
<p class="char" char="a">a</p>
<p class="char" char="c">c</p>
<p class="char" char="k">k</p>
<p class="char" char="o">o</p>
<p class="char" char="v">v</p>
<p class="char" char="e">e</p>

FWIW, here's my take on this doing it only with CSS: http://codepen.io/ricardozea/pen/uFbts/

Several notes:

  • The main reason I did this was to test myself and see if I was able to accomplish styling half of a character while actually providing a meaningful answer to the OP.

  • I am aware that this is not an ideal or the most scalable solution and the solutions proposed by the people here are far better for "real world" scenarios.

  • The CSS code I created is based on the first thoughts that came to my mind and my own personal approach to the problem.

  • My solution only works on symmetrical characters, like X, A, O, M. **It does not work on asymmetric characters like B, C, F, K or lower case letters.

  • ** HOWEVER, this approach creates very interesting 'shapes' with asymmetric characters. Try changing the X to a K or to a lower case letter like an h or a p in the CSS :)

HTML

<span class="half-letter"></span>

SCSS

.half-character { 
  display: inline-block;
  font: bold 350px/.8 Arial;
  position: relative;

  &:before, &:after {
    content: 'X'; //Change character here
    display: inline-block;
    width: 50%;
    overflow: hidden;
    color: #7db9e8;
  }
  &:after {
    position: absolute;
    top: 0;
    left: 50%;
    color: #1e5799;
    transform: rotateY(-180deg);
  }
}

This can be achieved with just CSS :before selector and content property value.

.halfed, .halfed1 {
  float: left;
}

.halfed, .halfed1 {
  font-family: arial;
  font-size: 300px;
  font-weight: bolder;
  width: 200px;
  height: 300px;
  position: relative; /* To help hold the content value within */
  overflow: hidden;
  color: #000;
}




.halfed:before, .halfed1:before   {
  width: 50%; /* How much we'd like to show */
  overflow: hidden; /* Hide what goes beyond our dimension */  
  content: 'X'; /* Halfed character */
  height: 100%;
  position: absolute;
  color: #28507D;

}



/* For Horizontal cut off */ 

.halfed1:before   {
  width: 100%;
  height: 55%;
  
}
<div class="halfed"> X </div>

<div class="halfed1"> X </div>

You can also do it using SVG, if you wish:

var title = document.querySelector('h1'),
    text = title.innerHTML,
    svgTemplate = document.querySelector('svg'),
    charStyle = svgTemplate.querySelector('#text');

svgTemplate.style.display = 'block';

var space = 0;

for (var i = 0; i < text.length; i++) {
  var x = charStyle.cloneNode();
  x.textContent = text[i];
  svgTemplate.appendChild(x);
  x.setAttribute('x', space);
  space += x.clientWidth || 15;
}

title.innerHTML = '';
title.appendChild(svgTemplate);
<svg style="display: none; height: 100px; width: 100%" xmlns="http://www.w3.org/2000/svg" xmlns:svg="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" version="1.1">
    <defs id="FooDefs">
        <linearGradient id="MyGradient" x1="0%" y1="0%" x2="100%" y2="0%">
            <stop offset="50%" stop-color="blue" />
            <stop offset="50%" stop-color="red" />
        </linearGradient>
    </defs>
    <text y="50%" id="text" style="font-size: 72px; fill: url(#MyGradient)"></text>
</svg>

You can use below code. Here in this example I have used h1 tag and added an attribute data-title-text="Display Text" which will appear with different color text on h1 tag text element, which gives effect halfcolored text as shown in below example

enter image description here

body {
  text-align: center;
  margin: 0;
}

h1 {
  color: #111;
  font-family: arial;
  position: relative;
  font-family: 'Oswald', sans-serif;
  display: inline-block;
  font-size: 2.5em;
}

h1::after {
  content: attr(data-title-text);
  color: #e5554e;
  position: absolute;
  left: 0;
  top: 0;
  clip: rect(0, 1000px, 30px, 0);
}
<h1 data-title-text="Display Text">Display Text</h1>

Just for the record in history!

I've come up with a solution for my own work from 5-6 years ago, which is Gradext ( pure javascript and pure css, no dependency ) .

The technical explanation is you can create an element like this:

<span>A</span>

now if you want to make a gradient on text, you need to create some multiple layers, each individually specifically colored and the spectrum created will illustrate the gradient effect.

for example look at this is the word lorem inside of a <span> and will cause a horizontal gradient effect ( check the examples ):

 <span data-i="0" style="color: rgb(153, 51, 34);">L</span>
 <span data-i="1" style="color: rgb(154, 52, 35);">o</span>
 <span data-i="2" style="color: rgb(155, 53, 36);">r</span>
 <span data-i="3" style="color: rgb(156, 55, 38);">e</span>
 <span data-i="4" style="color: rgb(157, 56, 39);">m</span>

and you can continue doing this pattern for a long time and long paragraph as well.

enter image description here

But!

What if you want to create a vertical gradient effect on texts?

Then there's another solution which could be helpful. I will describe in details.

Assuming our first <span> again. but the content shouldn't be the letters individually; the content should be the whole text, and now we're going to copy the same ‍‍<span> again and again ( count of spans will define the quality of your gradient, more span, better result, but poor performance ). have a look at this:

<span data-i="6" style="color: rgb(81, 165, 39); overflow: hidden; height: 11.2px;">Lorem ipsum dolor sit amet, tincidunt ut laoreet dolore magna aliquam erat volutpat.</span>
<span data-i="7" style="color: rgb(89, 174, 48); overflow: hidden; height: 12.8px;">Lorem ipsum dolor sit amet, tincidunt ut laoreet dolore magna aliquam erat volutpat.</span>
<span data-i="8" style="color: rgb(97, 183, 58); overflow: hidden; height: 14.4px;">Lorem ipsum dolor sit amet, tincidunt ut laoreet dolore magna aliquam erat volutpat.</span>
<span data-i="9" style="color: rgb(105, 192, 68); overflow: hidden; height: 16px;">Lorem ipsum dolor sit amet, tincidunt ut laoreet dolore magna aliquam erat volutpat.</span>
<span data-i="10" style="color: rgb(113, 201, 78); overflow: hidden; height: 17.6px;">Lorem ipsum dolor sit amet, tincidunt ut laoreet dolore magna aliquam erat volutpat.</span>
<span data-i="11" style="color: rgb(121, 210, 88); overflow: hidden; height: 19.2px;">Lorem ipsum dolor sit amet, tincidunt ut laoreet dolore magna aliquam erat volutpat.</span>

enter image description here

Again, But!

what if you want to make these gradient effects to move and create an animation out of it?

well, there's another solution for it too. You should definitely check animation: true or even .hoverable() method which will lead to a gradient to start based on cursor position! ( sounds cool xD )

enter image description here

this is simply how we're creating gradients ( linear or radial ) on texts. If you liked the idea or want to know more about it, you should check the links provided.


Maybe this is not the best option, maybe not the best performant way to do this, but it will open up some space to create exciting and delightful animations to inspire some other people for a better solution.

It will allow you to use gradient style on texts, which is supported by even IE8!

Here you can find a working live demo and the original repository is here on GitHub as well, open source and ready to get some updates ( :D )

This is my first time ( yeah, after 5 years, you've heard it right ) to mention this repository anywhere on the Internet, and I'm excited about that!


[Update - 2019 August:] Github removed github-pages demo of that repository because I'm from Iran! Only the source code is available here tho...

  <div data-content="A CSS only solution..."></div>
  <div data-content="Try it on Firefox!"></div>

The idea is to apply an horizontal CSS mask for each character, that hides the first half of it [0 - 0.5em] and shows the second half [0.5em - 1em].

The width of the mask is mask-size: 1em to match the width of the very first character in the string. By using the mask-repeat: repeat-x, the same mask is applied to the second, third character and so on.

I thought that using the font monospace would solve the problem of using same-width letters, but I was wrong. Instead, I solved it by using the text-transform: full-width, that unfortunatelly is only supported by Firefox, I believe.

The use of relative unit em allows the design to scale up/down depending on the font-size.

Vanilla JavaScript solution for all browsers

If Firefox is not an option, then use this script for the rescue.

It works by inserting a child span for each character. Inside each span, a non-repeated CSS mask is placed from [0% - 50%] and [50% - 100%] the width of the letter (which is the width of the span element).

This way we don't have anymore the restriction of using same-width characters.

const
    dataElement = document.getElementById("data"),
    content = dataElement.textContent,
    zoom = function (fontSize) {
        dataElement.style['font-size'] = fontSize + 'em';           
    };

while (dataElement.firstChild) {
    dataElement.firstChild.remove()
}
for(var i = 0; i < content.length; ++i) {
    const
        spanElem = document.createElement('span'),
        ch = content[i];    
    spanElem.setAttribute('data-ch', ch);
    spanElem.appendChild(document.createTextNode(ch === ' ' ? '\u00A0' : ch));
    data.appendChild(spanElem);
}
#data {
    position: relative;
    top: 2em;
    height: 2em;
    font-size: 2em;
}

#data span {
    display: inline-block;
    position: relative;
    color: transparent;
}

#data span:before,
#data span:after {
    content: attr(data-ch);
    display: inline-block;
    position: absolute;
    top: 0;
    right: 0;
    bottom: 0;
    left: 0;
    text-align: center;
    color: initial;
}

#data span:after {
    color: red;
    -webkit-mask-image: linear-gradient(to right, transparent 0, transparent 50%, white 50%, white 100%);
    mask-image: linear-gradient(to right, transparent 0, transparent 50%, white 50%, white 100%);
}
Font-size:
<input type="range" min=1 max=4 step=0.05 value=2 oninput="zoom(this.value)" onchange="zoom(this.value)">

All solutions work by splitting letters and wrapping them in <span>. We don't have to split letters in two cases:

  • If font is monospace.
  • If vertical layout is used.

div {
  font-size: 80px;
  font-weight: bolder;
  color: transparent;
  padding: 0;
  margin: 0;
  background: linear-gradient(90deg, rgb(34, 67, 143) 0% 50%, #409FBF 50%);
  background-clip: text;
  -webkit-background-clip: text;
}

.one {
  font-family: 'Nova Mono';
  background-repeat: repeat-x;
  background-size: 45px;
}

.two {
  font-family: 'Gideon Roman';
  writing-mode: vertical-lr;
  text-orientation: upright;
  letter-spacing: -35px;
  height: 500px;
}
<!-- get the fonts -->

<div id='one' class="one">X-RAY Winter</div>
<div class="two">Minty</div>

Expected output, in case the fonts are not available:

I know use of background-clip and gradient has been already demonstrated in other answers, just putting the cases where you don't have to split the letters.
