1. Images must have alternative text. 43.03%
To express their purpose and meaning to screen reader users, all images must include alternative text.
2. Buttons must have discernible text. 22.58%
For screen reader users, buttons must include recognizable text that specifies the destination, purpose, function, or action.
3. Certain ARIA roles must be contained by particular parents. 9.60%
Certain ARIA roles must be enclosed by specific parent roles in order to carry out their intended accessibility functions.
4. Zooming and scaling must not be disabled. 8.94%
The user-scalable="no" parameter in the <meta name="viewport"> element must not be used since it prevents text scaling and zooming, which are necessary for individuals with impaired vision.
5. Elements must only use supported ARIA attributes. 4.78%
Not all ARIA role-attribute combinations are valid. Each role must have its required qualities.
6. Certain ARIA roles must contain particular children. 4.39%
Some ARIA role values in parent elements must contain specific child elements and role values in order to execute the intended accessibility function.
7. Form elements must have labels. 3.39%
Each form element must have a label element attached with it.
8. Select element must have an accessible name. 1.45%
A label element with a programmatic association must be included for each select element.
9. ARIA attributes must conform to valid values. 1.12%
Valid values must be present for ARIA properties that begin with aria-.
To fulfill the intended accessibility purpose, these values must be written correctly and relate to values that make sense for a certain property.
10. Non-empty <td> elements in larger <table> must have an associated table header. 0.71%
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.
