I have created a CSS style class:
.btn {
color:#050;
font: bold 84% \'trebuchet ms\',helvetica,sans-serif;
background-color:#fed;
border:1px soli
If you don't want to explicitly set all the styles, but want to use the styles already defined in some pre-existing class (for example the bootstrap btn-default class), you could do something like this:
In my case this was what I was looking for, although I'm sure there is some sort of caveat about doing it this way, or you'd expect it was something doable directly from CSS.
