Programming in ASP.NET 4.0 and I thought I would start with CSS3 on one of my client site.
I first made a fiddle which worked beautifully. Styles used in the fiddle are
.newmainblock{
background:rgb(254,254,253) ; /* Old browsers */
background: -moz-linear-gradient(top, rgba(254,254,253,1) 0%, rgba(220,227,196,1) 42%, rgba(174,191,118,1) 100%); /* FF3.6+ */

Now I copied that to my css inside my visual studio and ran it. To my dismay I found that I could not see a newbuttonbar at all. I asked firebug and they told me there is no newbuttonbar defined at all.
Also even though the style is not applied its still displayed in Firebug CSS console
At last I found the reason as this. ( I am not sure if this is correct )
The CSS editor complains that newmainblock is
missing an opening brace ‘({)’ after the selector in the style rule
So it omits the tag that just comes after newmainblock. That is newbuttonbar. All the other styles are taken into account. Why this happens, what am I doing wrong and how to correct it?
On an unrelated sidenote DTD of my ASP.NET generated page as well as my fiddle is XHTMl1.0
There are some invalid characters in your CSS after the closing curly braces. Your code editor just isn’t showing them. Try the page in Chrome, then open the web inspector (F12). Switch to the “Resources” or “Sources” tab and take a look at your CSS. You’ll see what I mean.
Here’s the fixed CSS:
