In most circumstances the website is fully keyboard accessible. As specified within thesection, skip links are being added where appropriate to aid navigation and interacting with most features is possible through keyboard use alone.
When navigating an experiment booking page, once a 'Next week', 'Next day' or 'Previous day' link is selected, the screen focus is not visible and it is not clear where the focus is located on the screen, it also does not alert screen reader users which element is currently in focus or where the cursor is located. This does not meet section 2.4.7 of the WCAG criteria. To regain clear screen focus, pressing the TAB key selects the next appropriate 'Next week', 'Next day' or 'Previous day' link.
