Understanding the :active Pseudo-Class
The :active pseudo-class in CSS applies styles to an element during the moment it is being activated by the user. This typically occurs when a user clicks or taps on a button, link, or other interactive element. It provides immediate visual feedback for the interaction.
In this example, the button briefly changes its background color and slightly shrinks when pressed, and the link changes color while being clicked.
Use :active to provide instant visual feedback when users interact with elements.
Combine with :hover for a smooth transition from hover to active states.
Avoid relying solely on :active for accessibility or critical functionality, as touch devices may handle activation differently.
Use subtle animations or transformations to enhance the perception of interactivity.
