How Do CSS \'and\' (&&) and \'or\' (||) Selectors Work?

Understanding CSS "and" and "or" Selectors

In CSS, you can use "and" and "or" operators to combine multiple selectors and apply styles based on specific conditions.

Using "and" Operator (&&)

The "&&" operator (also known as "logical AND") looks for elements that match all the specified conditions. For example, to select input elements that are not of type "radio" or "checkbox," you would write the following selector:

input:not([type="radio"]) && input:not([type="checkbox"])

This selector ensures that the elements don't have the "radio" or "checkbox" types.

Using "or" Operator (||)

The "||" operator (also known as "logical OR") looks for elements that match any of the specified conditions. For example, to select input elements that are either of type "text" or "submit," you would write the following selector:

input[type="text"], input[type="submit"]

This selector ensures that the elements have the "text" or "submit" types, regardless of their other attributes.

Usage Examples

• To style all input elements except those with the "disabled" attribute: input:not([disabled])
• To select paragraphs that are both centered and have the "important" class: p.important:center
• To style div elements that have either the "error" or "success" class: div.error, div.success

Understanding the correct usage of "&&" and "||" operators is essential for creating precise and efficient CSS selectors.
