responsibility: Design
Collection of success criterion where the responsibility falls under visual and interaction design decisions.
1.4.1 Use of Color
Colour shouldn’t be the only thing used to convey meaning.
1.4.10 Reflow
Content remains readable and usable without requiring horizontal scrolling when viewed at 320 CSS pixels wide (typically equivalent to a mobile viewport) by adapting layout and reflowing text.
1.4.11 Non-text Contrast
Usable components like form fields and buttons, and graphics like pie charts and line graphs should have a contrast ratio of 3 to 1.
1.4.12 Text Spacing
Users can increase letter, word, line, and paragraph spacing without cutting off content or breaking functionality.
1.4.13 Content on Hover or Focus
Tooltips can be dismissed, usually via the esc key, the text in the tooltip can be selected, and they don’t time out on their own.
1.4.3 Contrast (Minimum)
Text has a contrast ratio of 4.5 to 1. Large text can be a 3 to 1 ratio if it’s over 24px, or bold and over 19px.
1.4.4 Resize Text
Text can be resized up to 200% without loss of content or functionality, except for captions and images of text.
1.4.5 Images of Text
Text is actual text; not images of text.
1.4.6 Contrast (Enhanced)
Text has a contrast ratio of 7:1 to 1. Large text can be a 4.5 to 1 ratio if it’s over 24px, or bold and over 19px.
1.4.8 Visual Presentation
For blocks of text, justification should be avoided, line-height should be at least 1.5, width should not exceed 80 characters, and users should be able to set text and background colors.
