Accessibility errors

[closeyetfar]

Do you plan on making the Bookreader pass the WAVE accessibility tool? There is missing alt text, empty buttons and 1 contrast error.

Since this issue was created a few years ago, several important accessibility issues remain (this is not a comprehensive list):

• The clickable controls (located at the bottom) for a book should be able used and configured by a user only using a keyboard. Currently, they are very limited. Only Zoom in/out and changing pages can be done through the keyboard.

For example, if a user does not have a mouse/trackpad or cannot use one, they cannot toggle from one to two page viewing, or read the book aloud using the audioplayer built into the bookreader !

• The buttons should also be focuseable elements. This would provide a visual indication that the current active setting/element is and this also provide an audible notification which element is currently active and can be toggled by the user.

I tested using https://archive.org/details/birdbookillustra00reedrich (Which according to the readme as of this writing, should be using 5.0).

Tested using Chrome 90 and Firefox 89. I also was able to reproduce the same issues in BookReader 4.40.2 as well.
