编译时Visual Studio中的CSS样式错误

Question

Whenever I use CSS3 style commands (like Box-shadow, Box-Sizing, background gradient,etc ) in my Visual Studio 2010 projects and compiles it, VS shows one or more errors regarding CSS3 styles. How can I overcome this behavior of Visual Studio?

Answer 1

You can turn off CSS validation errors in Visual Studio from Tools menu. Select Tools > Options and perform the action shown in the following image.

Answer 2

I have a better answer for you than the currently accepted answer. It's actually just a small change to said answer and here it is. Just check the "as warnings" box. So it doesn't show up as an error (which is good because it ain't one), but it does show up in your pleasantly-ignorable warnings list still.

Answer 3

Up the top there is drop down text box (next to comments in toolbar). Open that and see if you have HTML5/CSS3 in there. If not, you have to download it from MSDN.
