Attribute Selectors.


  Advanced selectors in CSS allow for more specific and precise styles. Attribute selectors allow you to apply styles based on the value of a specific attribute of an element.


Syntax


The basic syntax for using an attribute selector is:
[attribute="value"] { css-properties }
Attribute selectors include: [attribute], [attribute="value"], [attribute^="value"], [attribute*="value"], etc.

Example:
  li[class]
    { font-size: 200%;}
  li[class="a"]
    {background-color: yellow;}
  li[class~="a"]
    {color: red;}

Purpose


Attribute selectors allow you to apply specific styles to elements based on the value of a given attribute. Examples:


  • Select links pointing to a specific site.
  • Style buttons based on their data type.
  • Apply styles to input fields with a specific value.
