I would generally say Carousels should not be tab panels. Here is a link to a WAI tutorial on how to create Carousels

I was having them mark up the carousel as a tab panel. There was already some weird aria in there, including marking the slides up as role="option". The aria-label was for a series of buttons, one for each tab, that have no text equivalent. I wanted them labeled as "slide 1 of 5" etc.

Was their specific concern that it would impact how long it takes the page to load or how it impacts the performance after the page has loaded?

I think I missed the suggestion you provided to them.

IF your solution is complex and requires a lot of code or other resources, it could have a noticeable impact to page load time. However, there are usually things you can do to mitigate the issue. Sometimes, smaller changes can have an impact on page load time, but then the problem is usually how the developer is managing the resources and by handling the resources differently they can manage the page load times better.

You might also want to ask them questions on why they think the additional accessibility improvements would impact performance. They may have real or perceived concerns, but by knowing the details you might be able to resolve the concerns for them.

Thanks,
Tim



I didn't catch what your suggestion was?

I was just told by a development team that they did not implement my accessibility suggestion because (in part) " in our experience it could affect performance when loading the page" Has anyone heard of anything like this?
