Hi all, I placed older SC text into the CFC - The current SC text for this one is: [1] Essential <https://rawgit.com/w3c/wcag21/user-interface-component-contrast-minimum_ISSUE-10/guidelines/index.html#dfn-essential>visual identifiers ofuser interface components <https://rawgit.com/w3c/wcag21/user-interface-component-contrast-minimum_ISSUE-10/guidelines/index.html#dfn-user-interface-component>have acontrast 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:*Acontrast 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 3CSS pixels <https://rawgit.com/w3c/wcag21/user-interface-component-contrast-minimum_ISSUE-10/guidelines/index.html#dfn-css-pixel>, for theessential <https://rawgit.com/w3c/wcag21/user-interface-component-contrast-minimum_ISSUE-10/guidelines/index.html#dfn-essential>visual identifier. * *Inactive:*Disabled or otherwise inactiveuser interface components <https://rawgit.com/w3c/wcag21/user-interface-component-contrast-minimum_ISSUE-10/guidelines/index.html#dfn-user-interface-component> * *User agent control:*The color(s) of the user interface component and any adjacent color(s) are determined by the user agent and are not modified by the author. Notes§ <https://rawgit.com/w3c/wcag21/user-interface-component-contrast-minimum_ISSUE-10/guidelines/index.html#user-interface-component-contrast-minimum> * Examples ofessential <https://rawgit.com/w3c/wcag21/user-interface-component-contrast-minimum_ISSUE-10/guidelines/index.html#dfn-essential>visual indicators ofuser interface components <https://rawgit.com/w3c/wcag21/user-interface-component-contrast-minimum_ISSUE-10/guidelines/index.html#dfn-user-interface-component>may include (a border, edge, or icon), current value (such as non-text visual indication of aria-valuenow on a slider) and current state (such as selection indicator, focus indicator) or other essential visual indication (which do not rely on color alone). * Under consideration: simplify this Success Criterion by setting the minimum color contrast requirement to 3:1 and removing any need for measuring thickness. * Under consideration: will review to see if it is possible to combine with proposed WCAG 2.1 SC 1.4.11 Graphics Contrast.
