How Can I Select HTML Elements with Multiple Specific Attributes in CSS?

Refining CSS Selectors with Multiple Attribute Matching

In CSS, attribute selectors enable the precise selection of HTML elements based on their attributes. When dealing with multiple attributes, the following query may arise:

Q: How do I select HTML elements that have both a specific attribute name and value? For instance, I want to target input elements with "name=Sex" and "value=M".

A: To match multiple attributes in a CSS selector, simply append attribute selectors with their desired name and value pairs. In your example, the correct syntax is:

input[name=Sex][value=M]

This selector will select input elements with "name=Sex" and "value=M" attributes. Other input elements with different attributes, such as "name=Sex" and "value=F," will not be selected.

The W3C standard further elaborates on multiple attribute selectors: "Multiple attribute selectors can be used to refer to several attributes of an element, or even several times to the same attribute."

For example, this selector targets SPAN elements where the "hello" attribute equals "Cleveland" and the "goodbye" attribute equals "Columbus":

span[hello="Cleveland"][goodbye="Columbus"]

Note that quotation marks are required around attribute values if they are not valid identifiers.

In summary, using multiple attribute selectors allows you to precisely refine CSS selectors by matching elements with specific attribute combinations.
