Q: What’s the purpose of 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. /* Change button background while active (pressed) */ button:active { background-color: steelblue; color: white; transform: scale(0.98); /* slight press effect */ } /* Link color change on active */ a:active { color: darkred; } Click Me Click This Link 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.
