Pseudo Class
The Pseudo class is a CSS keyword added to the selector for defining special state of an element. Pseudo-classes style elements based on user interactions such as clicks or hover. They usually start with Colon, like :hover, used for targetting elements during mouse interactions and focus. The Pseudo class represents these conditions that cannot be targeted with a simple selector. The prefix “pseudo” refers to the virtual characteristic of the keyword. They can reduce the need for separate classes for different states to keep HTML lean and organised. In CSS3, introduction of structural pseudo-classes has expanded capabilities of CSS selectors, allowing more precise targeting of elements. They provide visual signals, feedback, and interactivity, making websites more engaging and user-friendly. Pseudo-classes are essential for creating modern-day websites by responding to user behaviour and queries.
