:after | ::after Redirect 1


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.


element:after  { style properties }  /* CSS2 syntax */

element::after { style properties }  /* CSS3 syntax */

The ::after notation was introduced in CSS 3 in order to establish a discrimination between pseudo-classes and pseudo-elements. Browsers also accept the notation :after introduced in CSS 2.


Simple usage

Let's create two classes, one for boring paragraphs and one for exciting ones. We can then mark each paragraph by adding a psuedo element to the end of it.

<p class="boring-text">Here is some good old boring text.</p>
<p>Here is some moderate text that is not either boring or exciting.</p>
<p class="exciting-text">Contributing to MDN is easy and fun.

.exciting-text::after {
   content:    "<- now this *is* exciting!"; 
   color:      green;

.boring-text::after {
   content:    "<- BORING!";
   color:      red;

The following example shows the use of the ::after pseudo-element in conjunction with the attr() CSS expression and a data-descr custom data attribute to create a pure-CSS, glossary-like tooltip. Checkout the live preview below, or you can see this example in a separate page.

<p>Here is the live example of the above code.<br />
  We have some <span data-descr="collection of words and punctuation">text</span> here with a few
  <span data-descr="small popups which also hide again">tooltips</span>.<br />
  Dont be shy, hove over to take a <span data-descr="not to be taken literally">look</span>.
    span[data-descr] {
        position: relative;
        text-decoration: underline;
        color: #00F;
        cursor: help;

    span[data-descr]:hover::after {
        content: attr(data-descr);
        position: absolute;
        left: 0;
        top: 24px;
        min-width: 200px;
        border: 1px #aaaaaa solid;
        border-radius: 10px;
        background-color: #ffffcc;
        padding: 12px;
        color: #000000;
        font-size: 14px;
        z-index: 1;
