Article Introduction：The hover effect of CSS can enhance the interactive texture through various techniques. 1. Use transition to achieve smooth animation, control the process of color, size and position change, and enhance the sense of nature; 2. Use pseudo-elements (::before or ::after) to create mask or scan effects to enrich visual feedback; 3. Combine transform and filter to achieve dynamic effects such as image enlargement, contrast changes and shadows; 4. Pay attention to mobile compatibility issues, avoid relying on hover to display key information, and consider JavaScript or alternative interaction solutions.

Article Introduction：CSS variables improve style management efficiency by defining reusable values. Developers use the --prefix to declare variables, usually define global variables in :root, and then reference them through the var() function, such as .button{background-color:var(--primary-color);}. Variables can be scoped as needed, such as redefining --text-color in .dark-mode to implement dark mode. JavaScript can dynamically update variables through setProperty to achieve interactive effects such as topic switching. When using it, please note that variable names are case sensitive, provide fallback values, avoid circular references, and reasonably control the scope of use to ensure maintenance and flexibility.

Article Introduction：To style SVGs using CSS, you first need to embed SVGs inline into HTML for fine control. 1. Inline SVG allows its internal elements such as or to be directly selected through CSS and to apply styles, while external SVG only supports global styles such as width and height or filters. 2. Use regular CSS syntax such as .class:hover to achieve interactive effects, but use fill instead of color to control the color, and use stroke and stroke-width to control the outline. 3. Use class names to organize styles to avoid duplication and pay attention to naming conflicts and scope management. 4. The SVG style may be inherited from the page, and can be reset through svg*{fill:none;stroke:none;} to avoid

Article Introduction：Defining link styles in sequence can avoid overwriting problems. The specific steps are: 1. First set the basic styles of: link (not accessed) and: visited (visited); 2. Then add transition effects and underscores through:hover; 3. Use:active (activate) to achieve click sinking or background changes; 4. Pay attention to the need to optimize the touch feedback of: active on the mobile terminal. At the same time, make sure that the color of the visited link has sufficient contrast and keep the overall style simple and unified.

Article Introduction：CSStransitions and transforms enhance user experience with smooth animations. 1. The transition requires specifying attributes and duration, which are often used for color or size changes; 2. The transformation includes movement, rotation, scaling, etc., which does not affect the document flow; 3. The combination of the two can create button hovering, menu switching and other effects; 4. The number of animations should be controlled during use to avoid performance problems; 5. It is recommended to use hardware-accelerated transform instead of directly modifying the position or size.

Article Introduction：CSS animation and transition can improve the web interactive experience, but it needs to be used in moderation. 1. CSS transition is suitable for smooth state changes in properties such as color and size. It is often used for button hovering and menu expansion. Transition attributes, duration, easing functions and triggering conditions need to be specified; 2. CSS animation defines keyframes through @keyframes and is controlled by animation attributes. It is suitable for complex behaviors such as loop playback or delayed execution, such as rotation loading animation; 3. When using it, pay attention to the balance between performance and user experience, avoid excessive complex animations, give priority to the use of hardware acceleration attributes such as transform and opacity, and consider accessibility, and appropriately control the animation duration and device compatibility.

Article Introduction：:hover pseudo-class is used to apply styles when hovering. 1. The basic syntax is selector:hover{style}, such as a:hover{color:red}; 2. Common uses include button color change, picture zooming and drop-down menu display; 3. Notes include inconsistent behavior of the mobile terminal, accessibility and performance optimization need to be considered; 4. In advanced examples, shadows, displacements and border changes are added when card hovering, and smooth animation is achieved with transition. The final effect is to improve the interactive experience but the full platform needs to be tested to ensure usability.

Article Introduction：opacity is an attribute in CSS that controls the overall transparency of an element, with values ranging from 0 (fully transparent) to 1 (fully opaque). 1. It is often used for the image hover fade effect, and enhances the interactive experience by setting the opacity transition; 2. Making a background mask layer to improve text readability; 3. Visual feedback of control buttons or icons in the disabled state. Note that it affects all child elements, unlike rgba, which only affects the specified color part. Smooth animation can be achieved with transition, but frequent use may affect performance. It is recommended to use it in combination with will-change or transform. Rational application of opacity can enhance page hierarchy and interactivity, but it should avoid interfering with users.

Article Introduction：PS feathering allows image edges to blur and transition, and is widely used, including processing selection edges, creating blurred backgrounds and halo effects. It uses an algorithm to gradually process the color and transparency of edge pixels, and the intensity is controlled by the feather radius. In actual use, the radius should be adjusted according to the image and effect to avoid excessive or insufficient. At the same time, pay attention to the accuracy of selection and the retention of details of high-contrast images, practice and observe more, and flexibly use feathering to improve the level of photo editing.

Article Introduction：prefers-reduced-motion is a CSS media query that detects whether the user enables the "reduced animation" setting in the system, thereby controlling the display of web animations based on user preferences. It is used in the form of @media(prefers-reduced-motion:value), common values include no-preference (default), reduce (reduce animation), and motion (enable animation). 1. Can be used to control transition animations (such as button color gradients), 2. Manage keyframe animations (such as rotation, fade), 3. Adjust page scrolling or parallax effects to improve the friendliness of visually sensitive users. Non-essential animations should be handled selectively when using them.
