We need to tweak some aspects of our Sharepoint site collection ("widen" the page, get rid of fixed/explicitly-sized elements).
I would like to test "probing" type changes in a separate environment, to quickly see what might work.
I have not been able to install Sharepoint on my dev machine (either at home or at work); we do the Sharepoint development via a Remote Desktop Connection to a Windows Server machine that has SP set up.
Anyway, what I'd like to do is create a "plain old" ASP.NET (not Sharepoint) app on my dev machine (locally) and test out my proposed HTML and CSS tweakings. Is this feasible and, if so, how?
Can I simply copy over the *.master pages (v4, minimal, default), the CSS files they reference and the HTML from various pages?
Is there a well-known way to test HTML/CSS changes for Sharepoint solutions in a non-Sharepoint solution?
There is no "easy" way to do this as far as I know.
However there is a possible solution a bit more tricky.
You can convert an HTML page to a Sharepoint master page and so on.
See this link for info about HTML to Sharepoint

You could easily just reverse this process. i.e. Sharepoint to HTML
This would allow you to test however you would like. Then just apply changes accordingly.
