A.22 WCAG 2.2 Success Criterion 2.5.5 – Target Size (Enhanced)

The sizes of target (e.g. button) are at least 44 by 44 Cascading Style Sheets (CSS) pixels, except when:

• Equivalent: The target is available through an equivalent link or control on the same page that is at least 44 by 44 CSS pixels;
• Inline: The target is in a sentence or block of text;
• User Agent Control: The size of the target is determined by the user agent and is not modified by the author;
• Essential: A particular presentation of the target is essential to the information being conveyed.

Before Rectification

Buttons are too small and difficult to tap.

After Rectification

The size of buttons is larger than 44 by 44 CSS pixels, so that users can tap the buttons easily.
