Hello Hannah!
I'm happy to help!
Will image overlap be an accessibility issue?
- I do not see a criterion in WCAG 2.0 that covers images that overlap. If they're decorative images and aren't needed to convey information, I would guess overlapping wouldn't be an issue.
If items in general overlap, will this be an accessibility issue?
- Here is information on what is technically a failure when overlapping text on an image. The best practice would be not to overlap text with text, but you could overlap text with an image if the contrast ratio is sufficient.
When applying focus order, should alt-text be included for all items that should be read?
- Great question! This WebAim article covers what needs alt next and what doesn't.
If alt-text is included in focus order is it also necessary to include text to speech?
- If a learner uses a screen reader, they won't need the text to speech since a screen reader will read the same content. If you do include text-to-speech, you'll want to make sure to include a text-based transcript.
