I am porting an existing 2003 project to 2005. Yesterday I found that some
of my Java script did not want to work. After eventually examining the HTML
view of the new and old form for differences, I noticed the DOCTYPE lines
pretty close to the top of the forms in HTML view differ. I removed the line
in the new form and my Java script worked. Today I noticed that a SPAN on a
new form with the width property set to 100% displayed about 1/4 over the
page, so I thought let me give the DOCTYPE line a shot, I removed it and the
SPAN displays perfectly. So, I am not sure if the DOCTYPE line generated by
VS2005 is evil or a new standard, but it surely causes problems. 6 1460

What you experience is called "quirks" mode. See http://www.quirksmode.org/css/quirksmode.html for more details.
Here's how IE 6 decides between quirks and standards compliant mode: http://msdn.microsoft.com/library/de.../en-us/dnie60/
html/cssenhancements.asp
Unfortunately, Visual Studio .NET 2002 and 2003 both use a default
DOCTYPE in ASP.NET that *enables* quirks mode.

What does all that mean for your HTML? If it requires quirks mode, it's
most likely broken...

The following JavaScript will allow the "width" style for spans to work in
all browsers, regardless of DOCTYPE:
<script type="text/javascript" >
var sps = document.getElementsByTagName("span");
for (var index = 0; index < sps.length; index++)
{
var sp = sps[index];
if (sp.className == "label")
{
var s = sp.style.width.substring(0, sp.style.width.indexOf("px"));
var i = (s - sp.offsetWidth) / 2;
if (sp.style.textAlign == "center")
{
sp.style.paddingLeft = i;
sp.style.paddingRight = i;
}
else if (sp.style.textAlign == "right")
sp.style.paddingLeft = i * 2;
else
sp.style.paddingRight = i * 2;
}
}
</script>

Hi Kevin, I should have mentioned that the span width is set on the style of
the span, thus:
<span style="WIDTH: 100%; .....>
So what I am saying is that Java script as well as normal HTML breaks with
the DOCTYPE settings used by VS2005.
The Java script that broke was (1) I've set a handler for the
document.onscroll and the event did not fire any more, and (2) on another
form I had something like theDiv.scrollIntoView().
Thanks in any case.

Hi Joerg, thanks for the links. That such a subtle thing can cause so many
problems (I debugged for quite a while before I stumbled upon it). When I
see a funny in a page now, first thing I do is to remove the DOCTYPE.
[Shame to him who thinks evil of it :-)]
Thanks.

So what's the general consensus when building VS2005 2.0 applications? Any
Target Schema suggestions? The Master is currently using this...
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >

It really depends on your both clients (browsers) and clients (the guys
giving you money).
Personally, I'd stay from quirks mode whenever possible, especially if
supporting multiple browser types is a requirement. One quirk that
works fine in one browser may cause disaster in another browser.
If accessibility is a requirement, you most likely have to render
standards compliant HTML -- many screenreaders don't work too well with
quirks mode HTML, and laws or regulations regarding accessibility may
simply prescribe that only standards compliant HTML is to be used for
certain types of web sites (government agencies etc.).
