DOCTYPE : safe to switch from Strict to Transitional?

Should I foresee major display problems across site?

[udon333]

Hi there,
I have recently built templates for quite a large content-managed website in XHTML strict. Unfortunately, I didn't foresee the back-end development(I'm told it's ASP.NET) to be churning out code that doesn't validate as strict DTD .
I have changed the doctype to XHTML Transitional in my static html templates, and so far I don't see any display problems, however I am worried that I may be overlooking something important/obvious, which could cause major problems with the site at this late stage.
So I would love to hear from anyone who has experience of this -
Could changing the doctype from Strict XHTML to Transitional break *anything* on a site - client- or even server-side?

Thanks

Welcome to WebmasterWorld udon333 :) Assuming you are changing nothing but the doctype itself (in other words, not adding an XML prolog or anything else before the doctype), then moving from XHTML 1.0 Strict to XHTML 1.0 Transitional will have virtually no effect.

The only potential problem could be with certain images within table cells in Firefox - the spacing might by very slightly altered. This, however, is usually easy to adjust.

That's a relief! Many thanks for your reply.

Why can't the developers output the code to your spec? As a programmer, I expect this of myself, it seems like you should be able to as well.
