Accessibility Guide for WCAG 2.0 Experimental
Since screen reader users cannot otherwise determine the structure of the document, styled p components must not be utilized to represent headings.
The fundamental goal of headers is to communicate the page’s organizational structure. Using varied text sizes allows sighted readers to see the structure. However, heading components must be marked up properly for screen reader users.
When header components are used correctly, both sighted and screen reader users will find it much simpler to traverse the page.
Users of screen readers can navigate between headings in the same manner that sighted users might skim a page to gain a sense of its contents. Users, especially those who use screen readers, can save a ton of time and stress by using well-written, logically-arranged headings.
Headings serve to explain the organization of the webpage, not only to draw attention to key text. They must be succinct, distinct, and numbered h1 through h6 in hierarchical sequence. For screen reader users, headers are a useful tool because of all of these characteristics.
Users of screen readers can navigate between headings in the same manner that sighted users might skim a page to gain a sense of its contents. Users, especially those who use screen readers, can save a ton of time and stress by using well-written, logically-arranged headings.
Due to the fact that search engines use headings when filtering, arranging, and showing results, headers offer advantages beyond just making a page more accessible. Making your website more searchable is another benefit of making it more accessible.
What this Accessibility Rule Checks
Verifies that paragraph components are not given the appearance of headers by using italic, bold, or font size.
Markup for data tables can be tedious and perplexing. There are several capabilities in screen readers that make it easier to navigate tables, but for these features to function properly, tables must be precisely marked up. Instead than utilizing a caption element, some tables visually imply a caption by employing cells with the colspan element.
Tables are announced in a certain way by screen readers. The potential for unclear or erroneous screen reader output exists when tables are not properly marked up.
Screen reader users cannot understand the purpose of the table visually when tables are not marked up with an actual caption element but rather use a colspan element on cells to visually indicate a caption.
What this Accessibility Rule Checks
Verifies that data tables are identified with table cells that utilize a colspan element to visually convey a caption.
Markup for data tables can be tedious and perplexing. Tables must be semantically marked up and have the proper header structure. Table navigation is made easier by features in screen readers, but for these capabilities to function properly, the tables must be precisely marked up.
Tables are announced in a certain way by screen readers. The potential for unclear or erroneous screen reader output exists when tables are not properly marked up.
Screen reader users are unable to correctly understand the relationships between the cells and their contents visually when tables are not adequately structured and marked up semantically.
What this Accessibility Rule Checks
Verifies the correct header structure and semantic markup of data tables.
