Re: CFC Add User Interface Component Contrast (Minimum) to Editors Draft

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.


Thanks

Josh
