Hi Tom,
Yes the search on DNN creative does not completely work, I will hopefully be addressing this over the next month.
If you are looking for any of the skinning tutorials, its easiest to go to:
http://www.dnncreative.com/Tutorial...fault.aspxand scroll down to the skinning section.
Minimising and creating efficient CSS codeand
Reducing the DotNetNuke CSS file sizes
is what you need.
The default.css file has not changed for a long time. - But as it happens some changes have been applied in 4.7! - Basically they have cleaned up some of the invalid code, but you can still apply shorthand techniques to it and reduce the file size further. - It's worth comparing the version available on DNN C with the current version and then just apply any differences. - This should save you quite a bit of time.
Thanks,
