Accessibility Guide for deafblind
Markup for data tables can be tedious and perplexing. Tables should be marked up correctly in terms of header format and semantics. 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 that each header cell is referred to as a header of a column or row in data tables by checking their markup.
To guarantee that text is pronounced correctly for screen reader users, the language given in the HTML content must be one of the valid languages.
The default language is chosen by users when setting up a screen reader. The screen reader assumes that a webpage is in the user’s default language when the language is not selected. When visitors access the website in more than one language and speak various languages, choosing a language becomes problematic. To ensure that website text is pronounced accurately, a language must be specified and validated.
Based on the pronunciation and traits of each language, screen readers employ distinct sound libraries for each one. If the papers specify which language(s) to read, screen readers can quickly switch between these language libraries. The screen reader will read the content in the user’s default language if the language is not set, which can be confusing.
What this Accessibility Rule Checks
The value of the lang
attribute must be correct.
