How important is it to you that your page validates with W3C standards?
I know I would like to be able to validate my pages, however constraints with DNN and access to the webconfig file make it difficult(read impossible) for me to make a valid page.
I suppose it is just frustrating when you are developing the site skin/template and all of the styles and html validate. But when you upload it to DNN and it converts the file to .ascx and applies 2 additional style sheets plus any other css files for custom modules and then the page no longer validates and ignores some style settings due to css inheritance. And then there are always cross-browser issues...
Does anyone else share this kind of frustration?
