How to change content on hover

Question

I've been playing around with this, and I thought it would be pretty simple. What I'm trying to do is hover over the 'NEW' label. Once in its hover state, change the content from 'NEW' to 'ADD' using only CSS.

body{      font-family: Arial, Helvetica, sans-serif;  }  .item{      width: 30px;  }  a{      text-decoration:none;  }  .label {      padding: 1px 3px 2px;      font-size: 9.75px;      font-weight: bold;      color: #ffffff;      text-transform: uppercase;      white-space: nowrap;      background-color: #bfbfbf;      -webkit-border-radius: 3px;      -moz-border-radius: 3px;      border-radius: 3px;      text-decoration: none;  }  .label.success {      background-color: #46a546;  }    .item a p.new-label span{    position: relative;    content: 'NEW'  }  .item:hover a p.new-label span{    display: none;  }  .item:hover a p.new-label{    content: 'ADD';  }

<div class="item">      <a href="">           <p class="label success new-label"><span class="align">New</span></p>      </a>  </div>

Here's a JSFiddle to show you what I'm working with.

Answer 1

The CSS content property along with ::after and ::before pseudo-elements have been introduced for this.

.item:hover a p.new-label:after{     content: 'ADD'; }

Answer 2

This exact example is present on mozilla developers page:

::after

As you can see it even allows you to create tooltips! :) Also, instead of embedding the actual text in your CSS, you may use content: attr(data-descr);, and store it in data-descr="ADD" attribute of your HTML tag (which is nice because you can e.g translate it)

CSS content can only be usef with :after and :before pseudo-elements, so you can try to proceed with something like this:

.item a p.new-label span:after{   position: relative;   content: 'NEW' } .item:hover a p.new-label span:after {   content: 'ADD'; } 

The CSS :after pseudo-element matches a virtual last child of the selected element. Typically used to add cosmetic content to an element, by using the content CSS property. This element is inline by default.
