So for example, I have a lovely button control:
<asp:Button ID="Button1" runat="server" Text="Button" />
Which when renders, is a lovely dull grey, nice and rectangular, etc, etc.
I know I can apply a new CSSClass to amend the CSS of said control, but where can I find the original CSS properties for this?
I appreciate this is a stupid question : )
This is the default style by the browser, not the ASP.NET control and you won’t find a style you can edit for each user of the web. For instance, if you look at an ASP.NET button in Mozilla and IE they will look a little different.
If you want to style them, use CSS as you said.
