Boolean HTML attributes

[Tonearm]

I was recently quoted this from the HTML 4.0 spec:

###
B.3.4 Boolean attributes

Authors should be aware that many user agents only recognize the minimized form of boolean attributes and not the full form.

For instance, authors may want to specify: <OPTION selected> instead of <OPTION selected="selected">
###

I didn't know about that at all. Do you guys all code your HTML according to the guideline above?

[korkus2000]

I do. Usually checked and selected are all that is needed. Some UAs just don't really look at the full attribute.

[Tonearm]

There aren't any browsers that *can* pick up on selected="selected" but not selected alone are there?

[DrDoc]

As of XHTML the full form is required.
Just keep in mind that "many user agents only recognize the minimized form" applies to old browsers.

[korkus2000]

>>to old browsers

Thats what I mean. If I am coding HTML 4 then I use the shorthand. XHTML like stated needs the full deal.

Ah, I saw <td nowrap="nowrap"> the other day, and wondered what that was all about.

I have always used <td nowrap> myself.

Thanks for the clarification.

Ok, I'm all clear on this now. Thanks a lot guys!
