Example of Skip Links:
A skip link is a hidden link that becomes visible when focused, allowing users to quickly jump to a specific section of a webpage. Here is an example of skip links:
Skip to main content
In the above example, when the user focuses on the skip link, it becomes visible, and clicking on it would take the user directly to the main content of the webpage.
Example of ARIA landmarks:
ARIA landmarks provide semantic information about the structure and purpose of different sections of a webpage. Here is an example of using ARIA landmarks:
| ARIA Landmark | Description |
|---|---|
role="banner" |
Identifies the banner section at the top of the webpage, typically containing the site logo and navigation. |
role="main" |
Indicates the main content section of the webpage. |
role="navigation" |
Defines the navigation section of the webpage. |
role="contentinfo" |
