Parentheses in CSS Selectors
Can parentheses be incorporated into CSS selectors? Specifically, in the instance of targeting a header with the text "Blockhead," can the selector be written as (.gumby > .pokey) h3?
Restricted Use of Parentheses
Parentheses are not valid operators in CSS selectors. They are reserved for functional notations, such as :lang(), :not(), and :nth-child().
Alternative for Parentheses in Sibling Relationships
In the provided example, parentheses are unnecessary. The selector .gumby > .pokey h3 is sufficient to select the desired header.
CSS selectors are read linearly. Combinators, like the ">" and " " used in this selector, do not have precedence. The selector can be interpreted as:
- Select an h3 element
- That immediately follows an element with the class "pokey"
- That is a child of an element with the class "gumby"
As both the .pokey element and the h3 element are children of the .gumby element in the provided HTML structure, this selector will correctly target the header with the text "Blockhead."
