Distinguishing link status: combine: link, visited,:hover,:focus, and:active to provide visual prompts. 3. Form control: Highlight the input box through:focus, and use:invalid and:valid to verify the status. 4.

How can you pause and resume a CSS animation?
Article Introduction：To pause and restore CSS animation, the most direct way is to dynamically switch the animation-play-state attribute using JavaScript. Controlling this property through JavaScript allows pause and playback to be achieved without restarting the painting. The specific steps include: 1. Add an event listener (such as button click); 2. Check the current animation status; 3. Dynamic switching status. In addition, if you only need to pause the animation during hover, you can implement it through the :hover pseudo-class combined with @keyframes, but this method is suitable for simple interactions and is not suitable for complex logic. For multiple animations or more complex scenes, you can process animations by index, reset animation state or manage states with CSS variables, and pay attention to performance

Usage tips include: prioritizing the use of transform and opacity to improve performance, ensuring the initial consistency is consistent with the target state, and setting the ease function reasonably. Frequently asked questions: enable hardware acceleration in a timely manner and reduce nesting, check the property name and initial value when the transition does not take effect, and repeat animation playback can be performed through inf
