Oh awesome LVTF,
As your time permits, please take a look at the latest, tighter, clearer
wording for Issue #10 User Interface Component Contrast
(Minimum)...inspired by Jared Smith :)
1.4.14 User Interface Component Contrast (Minimum)
All essential
<https://rawgit.com/w3c/wcag21/user-interface-component-contrast-minimum_ISSUE-10/guidelines/index.html#dfn-essential>
visual
identifiers that a user interface component
<https://rawgit.com/w3c/wcag21/user-interface-component-contrast-minimum_ISSUE-10/guidelines/index.html#dfn-user-interface-component>
is
interactive have a contrast ratio
<https://rawgit.com/w3c/wcag21/user-interface-component-contrast-minimum_ISSUE-10/guidelines/index.html#dfn-contrast-ratio>
of
at least 4.5:1 against the immediate surrounding color(s), except for the
following situations:
- *Thicker:* A contrast ratio
<https://rawgit.com/w3c/wcag21/user-interface-component-contrast-minimum_ISSUE-10/guidelines/index.html#dfn-contrast-ratio>
of
at least 3:1 is required where the minimum width and height are
at least 3 CSS
pixels
<https://rawgit.com/w3c/wcag21/user-interface-component-contrast-minimum_ISSUE-10/guidelines/index.html#dfn-css-pixel>,
for the essential
<https://rawgit.com/w3c/wcag21/user-interface-component-contrast-minimum_ISSUE-10/guidelines/index.html#dfn-essential>
visual
identifier.
- *Inactive:* Disabled or otherwise inactive user interface components
<https://rawgit.com/w3c/wcag21/user-interface-component-contrast-minimum_ISSUE-10/guidelines/index.html#dfn-user-interface-component>
are
exempt from this requirement.
Note about essential
<https://rawgit.com/w3c/wcag21/user-interface-component-contrast-minimum_ISSUE-10/guidelines/index.html#dfn-essential>
visual
identifiers that a user interface component
<https://rawgit.com/w3c/wcag21/user-interface-component-contrast-minimum_ISSUE-10/guidelines/index.html#dfn-user-interface-component>
is
interactive: Examples of visual indication that a component is interactive
include a border, edge, icon, focus indicator, selection indicator or other
visual indication (which do not rely on color alone).
"What changed?" you ask:
I answer:
"All essential visual identifiers of user interface components have a
contrast ratio of at least 4.5:1 against the immediate surrounding color(s)"
changed to
"All essential visual identifiers that a user interface component is
interactive have a contrast ratio of at least 4.5:1 against the immediate
surrounding color(s)"
Let me know if you have any questions or concerns.
Peace out,
Glenda
