Inside the Alt Tag
There is no such thing. Once again: alt is the attribute.
There are elements, tags, and attributes. They mean different things.
Notice the additional attribute--alt. What does the alt attribute or tag
do? Hover your mouse over the image to the left. Do you see the little
text box pop up? See what it reads? Does it look familiar?
No, I don't see it. That's because only Internet Explorer shows alt attributes
as tooltips, and it has been fixed in IE8:
"The alt attribute is no longer displayed as the image tooltip when the browser
is running in IE8 mode. Instead, the target of the longDesc attribute is used as
the tooltip if present; otherwise, the title is displayed."
If you want to see tooltip, use title attribute (most browsers show
this attribute as tooltip)
for that: http://www.w3.org/TR/html4/struct/global.html#adef-title
So, hover over the images in your website. Do they have the important
alt text included? At Thunder Data Systems, we adhere to proper coding
Good for you. Next step would be to stop calling attributes tags,
to check your code for adherence to standards (alt attribute is
required in HTML4,
so missing it will make code invalid. For purely decorative images alt
should be set
to empty string: alt="", better yet, these images belong to CSS, not HTML), and
remembering other browsers out there in which hovering over does not work.
