We run some automated accessibility tests to try to ensure best practices for visually impaired as well as accessibility's benefits for non-impaired users.
Here are the rules currently being reported:
meta-viewport- Regarding "Zooming and scaling must not be disabled",<meta name="viewport" content="...user-scalable=no">; this rule is ignored in tests, as it is a known issue. We do have our own zoom controls. It should also require a lot of work to refactor.color-contrast- Regarding "Elements must have sufficient color contrast", the following at least have been reported:#sidepanel_handle,#main_icon > span,#stroke_style.duplicate-id, - Regarding "id attribute value must be unique", the selector#fill_color > svg > defs > lineargradientis being reported, and it is due to multiple IDs withineditor/images/svg_edit_icons.svg(due to internal duplicates and/or because of cloning?).
