1728378 - Image elements with missing alt text

Status: RESOLVED FIXED

(Thunderbird :: Disability Access, defect)

Description

[Henry Wilkes (they/them) [:henry-x]]

There are some img elements with no alt attribute, nor a title. We should give these an appropriate alt text.

Side note: there are elements with a title attribute, but no alt. If an img must have a title, then it is usually preferable to leave the alt attribute unset, rather than set to "". This is because the accessibility tree will use the title as the accessible name, whilst the technical specification would mean that <img alt="" title="helpful name" /> would actually be ignored. Note that firefox does not currently follow this technical specification, see Bug 1700174, but we should still try to avoid it.

I think I'll widen the scope of this bug to include places where we are using background-image for non-presentational information, which should be <img> elements with non-empty alts. These are harder to track down though.

Henry, is bug 1743591 a side effect?

No it's not a side effect. I'll give my thoughts in the other bug.

We can close this considering the UI rebuild from scratch. Any other work should be done in dedicated bugs.
