ATTRIBUTE SELECTORS

Attribute selectors are used to apply style sheet declarations based on the presence of attributes or attribute values of an HTML element.

There are several types of attribute selectors, and CSS is capable of detecting attributes based on the following criteria:

• The presence of an attribute
• The value of an attribute
• Whether the attribute value begins with a specific string
• Whether the attribute value ends with a specific string
• Whether the attribute value contains a specific string anywhere in the value, be it at the beginning, end, or middle

The following sections examine each type of attribute selector in greater depth and provide examples of the syntax for each.
