#Selectors

dompdf supports the following CSS 2.1 selector syntaxes. dompdf also supports elements with multiple class attributes (e.g. <p class="red bold">foo</p> matches p.red and p.bold).

Note that the CSS selectors are case sensitive in dompdf (e.g. .foo will not match <div class="FOO">bar</div>)
