Making a plus sign with css

Question

I have a mockup for making what looks like a pretty simple plus sign. However, My css skills are not super great. Making the circle is no big deal but making the plus sign inside of it I can't seem to figure out. Here is what I'm trying to do.

Mockup

Here is what I currently have

Here is my code so far:

html

<div class=circle></div>

CSS

.circle {
    border-radius: 50%;
    width: 200px;
    height: 200px;
    background-color: rgb(44,108,128)
}

So pretty basic stuff but if anyone know how to add the plus sign you'd be making my night quite a bit nicer! Thanks for the help!

Answer 1

You may also consider a gradient:

possible example:

.circle {
  display: inline-block;
  vertical-align: middle;
  border-radius: 50%;
  width: 200px;
  height: 200px;
  background-image: linear-gradient(white, white), linear-gradient(white, white);
  background-repeat: no-repeat;
  background-position: center center;
  background-size: 20% 70%, 70% 20%;/* size it to a ratio(%) or static size (px, em, ..) */
  background-color: rgb(44, 108, 128)
}

.circle+.circle {
  width: 150px;
  height: 150px;
}

.circle+.circle+.circle {
  width: 100px;
  height: 100px;
}
.circle+.circle+.circle +.circle {
  width: 3em;
  height: 3em;
}
.circle+.circle+.circle +.circle +.circle {
  width: 1.5em;
  height: 1.5em;
}

<div class="circle"></div>
<div class="circle"></div>
<div class="circle"></div>
<div class="circle"></div>
<div class="circle"></div>

You can very well use ::after and ::before pseudo elements:

.circle {
  border-radius: 50%;
  width: 200px;
  height: 200px;
  background-color: rgb(44, 108, 128);
  position: relative;
}
.circle::after {
  content: " ";
  position: absolute;
  display: block;
  background-color: #fff;
  height: 10px;
  margin-top: -5px;
  top: 50%;
  left: 5px;
  right: 5px;
  z-index: 9;
}
.circle::before {
  content: " ";
  position: absolute;
  display: block;
  background-color: #fff;
  width: 10px;
  margin-left: -5px;
  left: 50%;
  top: 5px;
  bottom: 5px;
  z-index: 9;
}

<div class="circle"></div>

Based on the height of width of the <div>, the plus will be a responsive one.

Here's a solution which actually draws a '+' character in a font of your choosing.

It uses a flexbox to achieve horizontal and vertical centering.

.circle {
border-radius: 50%;
width: 200px;
height: 200px;
background-color: rgb(44,108,128)
}

.circle::before {
  content: "+";
  height:200px;
  width:200px;
  font-size:200px;
  display:flex;
  flex-direction:row;
  align-items:center;
  justify-content:center;
  font-weight:bold;
  font-family:courier;
  color:white;
}

<div class="circle"></div>
