Actual Results

Focus is not visible for most of the interactive elements such as "f365f297a61", "51935f3d546" and so on the page. A focus indicator is not visually available as the user tabs through these links using a keyboard.
As a result, users with learning and mobility impairments as well as those with low vision will not be able to easily find out which element currently has the focus.

Expected Results

Provide a clear visual indication to users when their focus moves from one interactive web page element to another. This will help all users while accessing the page content especially users with visual, mobility and learning impairments.
