Binding element selector

Class selectors can be used in conjunction with element selectors.

For example, you might want only paragraphs to appear as red text:

P.important {color:red;}

The selector now matches all p elements where the class attribute contains important, but no other type of element matches, regardless of whether the class attribute is present or not. The selector p.important is interpreted as: "all paragraphs whose class attribute value is important." Because the H2 element is not a paragraph, the selector of this rule does not match it, so the H2 element does not turn into red text.

If you do want to specify a different style for the H2 element, you can use the selector h2.important:

This is the end of p.important {color:red;} h2.important {color:blue;} on "HTML Class Selector usage instance Analysis". Thank you for reading.
