    ::after (:after) Redirect 1

    Summary

    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.

    Syntax

    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.

    Examples

    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;
    }

    Tooltips

    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>.
    </p>
    
        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;
        }
