#id #firstname Selects the element with id=“firstname”
* * Selects all elements
element p Selects all


element.class p.intro Selects all

elements with class=“intro”

element,element div, p Selects all
elements and all


element element div p Selects all

elements inside

element>element div > p Selects all

elements where the parent is a
