View Full Version : Problems with Internet Explorer and Lightbox

01-04-2010, 10:30 PM
Lightbox is working/looking great with my Mac browsers (Firefox, Safari), but I'm experiencing an issue with it in the current version of Internet Explorer for PC: Scrollbars appear around the display window which prevent the entire image from being viewed at once. I tried removing the dimensional attributes from the outer image container, but it didn't help.


Any help will be warmly received!

Go back to how it was before you tried to fix it. Use a valid URL DOCTYPE for your page like:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

It should be the very first thing in your page's source code, before the opening <html> tag.

Thanks, John. I'm new to the concept of "valid URL DOCTYPE" and to http://www.w3.org/. How do I determine a valid URL DOCTYPE?

Thanks again,

HTML 4.01 strict is very good. You may have better luck with the one I posted in my last message though. The main reason for a valid URL DOCTYPE in this case is to trigger IE's (6+) standards mode in rendering the lightbox. The URL in this case is a link back to the W3C's DTD for that DOCTYPE. This is required to trigger standards mode in IE, though the HTML 5 DOCTYPE, which is very simple and has no URL:


is supposed to trigger standards mode as well. I haven't tested it enough to be sure if it will be sufficient in this case, but you're welcome to give it a try.

Once you have a DOCTYPE, you can see if your page is valid for that DOCTYPE, but that's a whole other story, often not necessary, though generally a good idea.
