The home icon and discussion topic drop-down icon now have text that is
visible only to screen readers. The visual change between the icon and the
topic name with down-arrow is now achieved with the CSS visible property
instead of the opacity property, so only one at a time will be visible to
screen readers as well as visually.
Modal dialogs should manage keyboard focus, ensuring that users can't
tab out of the modal dialog and back into the page itself (effectively
moving “behind” the dimmed modal). On the last focusable element of the
dialog, return focus back to the first focusable element.
Also move the close button to the start of the dialog's section, making
it the first focusable URL, to ensure focus matches the visual
representation of the dialog.
The close button for the modal dialog was marked up as a paragraph,
containing a graphical text character, inside two div elements, with an
associated click event. This made the button unusable for keyboard
users.
Replaced <divs> with a link element (<a role="button"), adapted the CSS
accordingly, and updated the existing <a> modal close buttons.
Added a 'aria-hidden="true"' attribute to the modal initially, then
toggle the value of that attribute to "false" when the modal is shown.
Also remove the attribute when the modal is closed, whether it's through
a click on the close button or on the overlay.

Also adding the email description to the login page and applying the
same aria attribute to the correspondin input on that page.
From LMS-602:
> There is additional explanatory text, marked up in a span element after
> the email input. The input elements should be explicitly associated with
> this additional text using the aria-describedby attribute. This will
