/*
	Descendant selectors are used to match to any nested element. 
	Child combinators, on the other hand, only match to the direct 
	child element and are defined by the greater than symbol. 
	The selector on the right must be the direct child of the element 
	on the left.

  parent child {...}
  ancestor descendant {...}

</div>
=> Will select the first <strong> element

Select all elements with the class "class",

<div id="id">
