Customizing scrollbar appearance with CSS pseudo-elements
Article Introduction：Use CSS pseudo-element::-webkit-scrollbar to customize the scrollbar style, 1. Set the scrollbar width; 2. Define the track background color; 3. Set the slider color and rounded corners; 4. Add a hover effect; 5. Apply styles to specific containers. Firefox uses scrollbar-width and scrollbar-color for simple control. IE/old browsers need to accept the default style or use plug-ins instead.

Creating tooltips with pure CSS
Article Introduction：The method of implementing tooltip with pure CSS is: 1. Use nested HTML structure to wrap the trigger area and prompt content; 2. Control the display and hide of child elements through:hover; 3. Use absolute positioning to set the prompt box position; 4. Add animation to improve the experience; 5. Pay attention to z-index and multi-directional adaptation. The specific implementation includes setting .tooltip as relative positioning, .tooltiptext is hidden by default, becomes visible when hover, and can add transition to achieve fading and delay effects. At the same time, positioning in different directions is controlled through class names, but it should be noted that the effect of hover on the mobile side may be limited.

Animating elements with css transitions and keyframes
Article Introduction：The key to improving user experience in CSS animation is to choose transition and @keyframes reasonably. 1. Transition is suitable for simple state changes, such as button hover effect, which is achieved by defining attributes, duration, delay and speed curves; 2. @keyframes is suitable for complex animation sequences, such as loading animations, which controls the state of elements at different time points through multiple keyframes. 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

How does the ::before and ::after pseudo-elements allow for styling non-DOM content?
Article Introduction：CSS pseudo-elements::before and ::after allow insertion and styling of non-DOM content without modifying HTML. By setting content attributes, you can add decorative text or symbols before and after the content of the element, and apply styles such as fonts, backgrounds, positioning and even animations, such as adding colored "Note:" tags or button hover animations. Common uses include dynamic icons, prompt tags, form tags and UI effects. However, it should be noted that if the content is not set, the pseudo-element is invalid; it cannot interact through JavaScript; and does not support nested HTML structures.
