Details

Selectors:

• Type selectors, e.g. input selects all <input> elements.

• Class selectors, e.g. .index selects any element that has a class of "index".

• ID selector. #toc will match the element that has the ID "toc".

Combinators:

• Descendant combinator, i.e. the space, that combinator selects nodes that are descendants of the first element. E.g. div span will match all <span> elements that are inside a <div> element.
