Subject: [WebAIM] Testing Web pages with Screen Reader after Disabling CSS:

Hi All,
I am Ajeesh, working with IBM Accessibility Team, have number of
quarries regarding testing the Web pages after Disabling CSS, could
anyone help me please?
1. Once the CSS Disabled Web page will be rendered as same as DOM
Order, Since the Screen reader go with Linear reading order (DOM
order) do we have any extra benefits for doing Screen Reader
Testing after Disabling the CSS?

Yes, because if error messages or any other messages are hidden by CSS, they will be visible to a screen reader making the UI confusing and disorienting. The best example is display: none; or images.

2. After Disabling CSS Found some of the extra hidden Elements, as
these are intentionally hidden from the actual Web page - do we
needs to consider the Accessibility lags of these hidden Content?

Of course, as I mentioned in the previous questions. They can confuse an average computer user with a screen reader and make it harder for low vision visitors if they are trying to remove CSS to get rid of colors that are hard to see. Some low vision users are color-blind too.

3. Once the CSS Disabled -There are some Functional difference found
on Scripted Interactive Elements, as the actual Web page working
fine -really do we needs to consider these issues?

Of course, if they cause the user to be confused and disoriented. Keep in mind all of your audience with disabilities not just screen reader users.

What would be the objective to the Web page with Screen reader after CSS Off, kindly guide me.

Clean layout as if CSS is on. The same you mentioned in your introduction. Proper DOM structure that renders properly to a user.

Thanks in advance,
" Have a fantastic day "ahead"
