Selector is similar to the CSS selector, but only supports the following syntax.

ID selector: #the-id
class selector (can specify more than one in a row): .a-class.another-class
Child Element Selector: .the-parent and .the-child
Descendant selector: .the-ancestor .the-descendant
Descendant selectors across custom components: .the-ancestor and .the-descendant
The intersection of multiple selectors: #a-node, .some-other-nodes
