HTML Basic - Validation
I know this is a really basic question...
Are these the same f开发者_开发技巧or close -
<iframe src="includes/captcha/captcha.php"></iframe>
<iframe src="includes/captcha/captcha.php"/>
And
<div id="container_join_messages" class="shadow"></div>
<div id="container_join_messages" class="shadow"/>
Just wanting to see if I can drop the extra tag at the end and still validate.
Using this doc type
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
According to What are all the valid self-closing elements in XHTML (as implemented by the major browsers)? XHTML capable browsers support self-closing on every element. I've never tried validating such a document myself though.
