To stick to strict you simply cant use iframes. Simple as that.

Iframes are still used and needed for some purposes but still there are alot of different approaches you can use to leave them out and stick to stict.

The method Aleksandar describes is indeed a nice approach but not a native solution.

Ever tryed to get text in front of a flash movie ! well Iframes provide th answer and you can see a sample at http://www.Websitetips.eu on the home page.

Iframes are also usefull for custom AJAX calls.

<object type=”text/html” data=”http://www.robertnyman.com/” width=”680″ height=”250″&gt
<a href=”http://www.robertnyman.com”>http://www.robertnyman.com</a>
</object>

If you want to use object elements for images (I don’t recommend it but if you did) you can remove the IE boarders by setting the CSS via javascript (think it’s the only way).

function fixObjectImages () {
if(!document.getElementsByTagName) {
return;
}
var objs = document.getElementsByTagName('OBJECT');
for (n = 0; n


That is true for Firefox, but other web browsers might interpret that differently. Still, in the end, transitional is just what the name implies: a transitional phase, a bridge to the proper version.

Almost Standards Mode is identical to Standards Mode except for the way images are aligned in tables so given that you are actually coding properly then this shouldn’t be a problem at all.

So I guess it’s not too bad in the end, provided the person knows about the alignment difference.

I was going by this Doctype Grid but it’s good to know otherwise.

Hopefully I won’t have to use iframes, I definitely wouldn’t voluntarily.

Very valid points, and I totally agree.

Kanashii,

Without a doubt, I try not to use iframes in the code as well, but sometimes there ad-related or other issues/demands.

Also I’m fairly sure Transitional+URI will render in Standards Mode in all recent browsers

Absolutely not. Firefox/Mozilla and Opera will use an Almost Standards Mode which is different from Standards Mode. More information can be found in Gecko’s “Almost Standards” Mode and Activating the Right Layout Mode Using the Doctype Declaration.

The doctype doesn’t make your code sloppy, the coders do

Oh, definitely. But it just makes it harder to find, say, if another web developer has inserted formatting things in the HTML code (since all that crap will be allowed), instead of properly having it in a CSS file.

It’s a validation error because iframes are not defined in the specification for Strict doctypes so they shouldn’t work even though they do. If you absolutely must use iframes you should use a doctype that supports it.

Also I’m fairly sure Transitional+URI will render in Standards Mode in all recent browsers.

I don’t think anyone should be using iframes though. They are in the Transitional doctype so they can be transitioned out and I agree in all other circumstances that people shouldn’t use Transitional but when you must use iframes I think that it’s the one time it should be used.

You can still have perfect code that would validate under a Strict doctype when using a Transitional one if you want it to. The doctype doesn’t make your code sloppy, the coders do. : )

I agree.

Kanashii,

Simply put it’s about rendering modes, but also about allowing for sloppy coding if there are other external web develops on board the project. Basically, transitional is just meant for an overgoing phase, not to be a permanent solution.

I’d choose a strict doctype with a validation error any day over a valid web site with a transitional doctype.

For more information, please read:

HTML or XHTML?

No more Transitional DOCTYPEs, please

Chis,

Yep.

Pat,

Yes, I shy away from using them too.

I try, as much as possible, to write CSS that works on all browsers. With regards to iFrames, I only have one site that uses them and that’s only to shoehorn my Coldfusion coding into a non-Coldfusion site - I think I can live with that !

It works, and always will, and it’s more “Standards Compliant” then using an iframe in a Strict Doctype.

There’s nothing wrong with using Transitional Doctypes and HTML. The quality of the code depends on the code itself not what Doctype it uses.

Kind of seems people are beginning to think HTML is cursed and your code isn’t any good if you don’t use XHTML 1.0 Strict or higher.
