@leecalcote Could you please assign me this? I'll check the progress on previously created issues and start working on it.

[leecalcote]

Performance is our primary concern. Accessibility is our secondary concern.

Thanks for putting a light on this area, @aakankshabhende

@leecalcote the site is highly performant already. My apologies I had a browser setting that was giving faulty results, which I realised when my fixes were not improving performance.
I have sent up a PR for accessibility changes.
