Display Problems with Lightbox in Internet Explorer
Properly display and functioning of DMXzone Lightbox
I'm experiencing problems with properly display and functioning of DMXzone Lightbox in Internet Explorer e.g. it appears behind some elements, and appears above my page header, moving the header to the bottom of the page.
Most probably, your page is lacking a <!DOCTYPE!> tag before the starting
<html> tag. That way the browser uses Quirks mode where xmlns is
not rendered properly. Please check if the following :
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
exists on line 1 of your page.
By default Dreamweaver places that line in each document that it creates. Removing it causes your issue.
