Make utopian accessible to disabled users

There are many blind and otherwise disabled open source developers. We need to make the UI of utopian accessible to them.

One issue is keyboard accessibility, another are popups and other notifications that disappear on the screen. Utopian will have to modify the website but also require contributions to be accessible to disabled users. For example images need to have a usable alt text, videos will have to have captioning.

I ran a quick check tool on the main website and it came up with : https://achecker.ca/checker/index.php

2.1 Keyboard Accessible: Make all functionality available from a keyboard.

1.4 Distinguishable: Make it easier for users to see and hear content including separating foreground from background. Use of Color (A) Check 86: script may use color alone.

Using the AXE Plugin for chrome, https://chrome.google.com/webstore/detail/axe/lhdoppojpmngadmnindnejefpokejbdd

it came up with the following issues :

1. ARIA attribute is not allowed: aria-selected="false"
   https://dequeuniversity.com/rules/axe/2.4/aria-allowed-attr?application=AxeChrome
   This is in the li element with the class "ant-menu-item Topnav__item-write" and the role "menuitem" you will see the aria-selected="false" which is not allowed.
   

2. Required ARIA children role not present: listbox textbox
   So for searches aria expects a listbox to be in the child element.
   https://dequeuniversity.com/rules/axe/2.4/aria-required-children?application=AxeChrome
   

3. ARIA attributes must conform to valid values
   aria-activedescendant=""
   https://dequeuniversity.com/rules/axe/2.4/aria-valid-attr-value?application=AxeChrome
   

4. Buttons must have discernible text
   Location .EditorToolbar > button.ant-dropdown-trigger
   the font size button.
   

5. Elements must have sufficient color contrast
   Element has insufficient color contrast of 2.39 (foreground color: #99aab5, background color: #ffffff, font size: 13.5pt, font weight: normal)
   

6. element must have a lang attribute

7. Images must have alternate text
   example img[src$="utopian-logo-120x120.png"]

8. Form elements must have labels
   

9. Links must have discernible text
   

10. Zooming and scaling must not be disabled
