A declaration block starts with a left curly brace ({) and ends with the matching right curly brace (}).
In between, there must be a list of zero or more semicolon-separated (;) declarations.
A declaration block may contain an other declaration block.
In between the curly braces, there may be any tokens, except that :
#dw__toc {
/* Apply to the div childs of the dw_toc id */
> div {
font-size: 0.875em;
padding: .5em 1em 1em;
}
