Editing Style sheet (web development) (section)

===Accessibility===
Sites that use CSS with either XHTML or HTML are easier to tweak so that they appear similar in different browsers (Chrome, [[Internet Explorer]], [[Mozilla Firefox]], [[Opera (web browser)|Opera]], [[Safari (web browser)|Safari]], etc.).

Sites using CSS "[[Fault-tolerant system|degrade gracefully]]" in browsers unable to display graphical content, such as [[Lynx (browser)|Lynx]], or those so very old that they cannot use CSS.  Browsers ignore CSS that they do not understand, such as CSS 3 statements. This enables a wide variety of [[user agent]]s to be able to access the content of a site even if they cannot render the style sheet or are not designed with graphical capability in mind. For example, a browser using a [[Refreshable Braille display|refreshable braille display]] for output could disregard layout information entirely, and the user would still have access to all page content.
