Which is right in web-design?

Question

On drop down lists, etc. (pre-selected) is it:

selected="selected"

OR

selected="yes"

(I know in FF 3 and IE 7 they both work), but i mean to conform to the standards.

Thanks in advance

Answer 1

<option value ="opel" selected="selected">Opel</option>

Answer 2

It's like this:

<option value= "" SELECTED>my text</selected>

You could have just look this up on Google which would have saved you asking the question.

Answer 3

It depends.

You can validate your html/css at these addresses:

http://jigsaw.w3.org/css-validator/ - CSS

http://validator.w3.org/ - HTML

Of course, there's no need to validate PHPs :)
