The CSS class screen-reader-text

WordPress introduced the class .screen-reader-text in 2009 and extended the use in 2015. Joe Dolson wrote a good post with the extended use of the screen-reader-text class in WordPress 4.2.

Use Use

The screen-reader-text class is used:

  • to hide text from vision that is useful only for screen readers users.
  • for skip links for keyboard navigation before the link get focus [to-do: link to skip links article]

The CSS class screen-reader-text is a WordPress Generated Class. Each theme should have this style in its CSS. The colours, borders and padding of the focus style can be adjusted to the styling of the theme.

/* Text meant only for screen readers. */
.screen-reader-text {
  border: 0;
  clip: rect(1px, 1px, 1px, 1px);
  clip-path: inset(50%);
  height: 1px;
  margin: -1px;
  overflow: hidden;
  padding: 0;
  position: absolute !important;
  width: 1px;
  word-wrap: normal !important;

The CSS elements that are only visible on keyboard focus (like skiplinks):

.screen-reader-text:focus {
  background-color: #eee;
  clip: auto !important;
  clip-path: none;
  color: #444;
  display: block;
  font-size: 1em;
  height: auto;
  left: 5px;
  line-height: normal;
  padding: 15px 23px 14px;
  text-decoration: none;
  top: 5px;
  width: auto;
  z-index: 100000; /* Above WP toolbar. */

Explanation of some of these CSS properties: Explanation of some of these CSS properties:

  • Set width and height to 1 pixel, because some screen readers don’t announce an element with a size of 0 pixels.
  • margin: -1px; to hide it completely from sight
  • word-wrap: normal; to avoid screen readers reading the text letter for letter, as the text is placed in a 1 pixel wide space. Many screen reader and browser combinations announce broken words as they would appear visually.
  • clip is deprecated, but is added to support older browsers that don’t support clip-path yet.

Note: display: none; and visibility: hidden; hide text from screen, but also for a screen reader, so can’t be used to give extra information to screen reader users.

Practical examples Practical examples

Invisible text to make a link meaningful out of context:

<a href="your-url">
  Read more
 <span class="screen-reader-text"> about cute kittens</span>

A caption of a table:

  <caption class="screen-reader-text">The cities of WordCamp Europe</caption>

A heading to make the heading structure meaningful and understandable, this also prevents an overload of H2s and gives the heading structure more context:

  <h2 class="screen-reader-text">Contact Information</h2>
  <h3>Social media</h3>

Note: If you include screen-reader-text as a part of a string in your WordPress theme, make sure the construction is translatable (see I18n for WordPress Developers). The word order may vary in different languages.
