Hi,
Are you saying that you can't use display: none and visibility: hidden as
inline attributes, but that we can use them in CSS classes? I'm confused.
Thanks.

Hi,
In my example yes. However, you could add a class that hides the content
visibly, but keeps it available to screen-reader users. You cannot do display:
none or visibility: hidden, or it will be ignored.

I've never used @longdesc for long descriptions. And, in fact it is currently
not of html5, it has been removed. However, that decision may be reversed.
The longdesc attribute must be given a URL. The URL is then accessed by AT in
order to get the description, taking people away from your page.
I recommend using aria-describedby, but this is only supported by newer
technologies.
Example:
<img src="cat.jpg" alt="A cat" aria-describedby="description-1" />
<p id="description-1">This is a beautiful cat sitting on a chair</p>
This programmatically associates the image with its long description.

Ok, what's your thoughts on the longdesc (Long Description) in place of the
"alt" for longer more meaningful narratives?

Hi JC,
The alt tag, first of all, is really not technically a tag. It's an attribute.
The same with the title attribute.
The difference, technically, between them is that alt flashes the description
in place on the screen when someone rolls a mouse over the tag that has the alt
attribute. With the title attribute, when the mouse rolls over the tag, a tool
tip pops up after a very short while.
For accessibility, it is recommended that the alt attribute be used for short,
succinct descriptions. For accessibility, it is recommended that the title
attribute be used for longer descriptions. In practice, though, you should most
often use alt, because if JAWS sees alt, it doesn't look for title by default.
If it sees title, it doesn't look for alt, even though web standards say that
both are supposed to be exposed and used.
Also, practically speaking, you can often use title on radio buttons when
screen space is cramped, visually.
A further note about the lack of screen reader support is that title is allowed
to appear on just about any HTML tag, but screen readers only support it on a
very few tags, most especially form controls, hyperlinks, and images.
Consequently, those of us who help make web sites accessible look bad when we
speak out of one side of our mouth and advocate for standard coding practices,
then out of the other side of our mouth, we say "Don't do that, because screen
readers haven't caught up to standards that have been in place since 1999."
That's a little soap box with me. Sorry to rant.
Thanks.
Jim

Sorry, I meant to say the difference between "title" and the "alt" text tag?
