  • How do you trigger a CSS transition?
    How do you trigger a CSS transition?
    To trigger CSS transition animation, you need to define the transition property and change the declared animated properties. 1. Define transition properties: Use transition or transition-property in CSS to specify the attributes and duration and duration to be animated; 2. Change the attribute value: Change the attribute value through:hover, JavaScript, pseudo-classes, etc.; 3. Pay attention to performance and compatibility: Avoid using transition:all, select properties that can be rendered efficiently, such as transform and opacity, and ensure that the initial state is defined. The browser will only execute it when the property value changes and the property is included in the transition declaration.

  • How can I style form inputs based on their state, like :checked or :invalid, using CSS Selectors?
    How can I style form inputs based on their state, like :checked or :invalid, using CSS Selectors?
    To style the different states of form input (such as selected, invalid or focused), the CSS pseudo-class should be used. 1. Use the checked pseudo-class to set styles for selected check boxes or radio buttons; 2. Use the:invalid pseudo-class to set styles for fields that have not passed the verification, combined with: user-invalid can be applied after user interaction; 3. Use the:focus and:hover pseudo-classes to enhance availability and accessibility; 4. Multiple pseudo-classes can be combined to implement multi-state style design, such as matching invalid and focused states at the same time. These methods can achieve dynamic style changes without JavaScript.

  • What does the overflow property control?
    What does the overflow property control?
    The overflow property of CSS is used to control how the container content is displayed when overflowing. Its core answer and detailed description are as follows: 1. overflow:visible (default) allows content to overflow the container and remain visible, suitable for situations where no content wants to be hidden or cropped; 2. overflow:hidden hides content beyond the boundary of the container, suitable for maintaining visually closed areas; 3. overflow:scroll always adds scroll bars, regardless of whether the content overflows, suitable for areas where scrolling behavior is required; 4. overflow:auto only displays scroll bars when the content actually overflows, suitable for content with dynamic or uncertain size; 5.

  • What is the clamp() function and how is it useful for responsive design?
    What is the clamp() function and how is it useful for responsive design?
    CSS' clamp() function realizes dynamic adjustment in responsive design by setting the minimum, preferred values ??and maximum values. It allows properties such as font size, spacing, etc. to smoothly adapt to different screen sizes. For example: font-size: clamp(1rem, 2.5vw, 2rem) means that the font is not less than 1rem on the small screen and not more than 2rem on the large screen, and 2.5vw is preferred for scaling. In addition, clamp() can also be used to control numerical properties such as inner margins and widths, such as padding: clamp(16px, 5%, 32px) to ensure that the inner margins maintain a reasonable range on different devices. Its browser support is good and is suitable for modern mainstream browsers. It is recommended to use it with relative units and
