lightbox overlay not scrolling down in IE7

**polvan** · 01-26-2009, 10:31 AM

I am using Lightbox v2.03 http://www.dynamicdrive.com/dynamici...box2/index.htm
it is working very well in FF, but in IE7 the overlay is not scrolling down : the overlay is only screenheight, when i scroll down it disappaers.
The page is this : http://www.captain-africa.com/nl_foto_Burkina_Mali.htm
Can anyone help me out ?
Thanks a lot

No problem here in IE 7.

the problem is here :
the width and height of the overlay are calcualted to equal the document size. In IE there was a glitch with this.
As I use the lightbox just on a few pages with all more or less the same size, I made the height into a constant value.
It is a crude solution to the problem

You might not have that problem with a valid document. Try replacing:

Code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" 
    "http://www.w3.org/TR/html4/strict.dtd"> 
<html xmlns="http://www.w3.org/1999/xhtml" lang="en">

with:

Code:

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

Thanks jscheuer1
but this doesn't change it. Also it interferes with my menu (HVmenu, from here) in FF3.
tahnks anyway

That's funny because with a valid DOCTYPE declaration on the DD demo page for this script, there isn't that problem either. Try validating your markup.

still i use the doctype provided with the HV menu, otherwise the HV menu does not work so well in FF, though all is OK in IE

Well yes, when other older scripts are involved things can get tricky. I do try to remain sensitive both to that, and to the fact that not everyone can and/or will take the time to upgrade to valid code.

So I'm not making any demands. I just wanted to point out for you and possibly for others that many modern scripts like Lightbox (which is far from perfect) work best in a valid coding environment.

Once you elect not to maintain such an environment, the number of required fixes, and their specificity tends to grow, making maintenance more time consuming.
