How to change content on hover

Questions:

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>
Answers:

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';
}

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.

This little and simple trick I just learnt may help someone trying to avoid :before or :after pseudo elements altogether (for whatever reason) in changing text on hover. You can add both texts in the HTML, but vary the CSS ‘display’ property based on hover. Assuming the second text ‘Add’ has a class named ‘add-label’; here is a little modification:

span.add-label{
 display:none;
}
.item:hover span.align{
 display:none;
}
.item:hover span.add-label{
 display:block;
}
