  • Creating responsive tables with CSS
    Creating responsive tables with CSS
    Responsive tables can be implemented in three ways: first, use media query to adjust the layout, change the table structure to vertical display and label the data type with data-label. Secondly, horizontal scrolling is achieved through overflow-x. Suitable for the situation where there is a lot of content without re-arrangement. Finally, combine front-end frameworks such as Bootstrap's .table-responsive class to simplify development and have good compatibility. Select the appropriate method according to project needs.

  • Creating tooltips with pure CSS
    Creating tooltips with pure CSS
    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.

  • Controlling CSS Variable scope and fallbacks
    Controlling CSS Variable scope and fallbacks
    Controlling the scope of CSS variables can avoid naming conflicts and improve maintenance. 1. Define the variable in a specific parent element rather than in root, such as .button{--btn-bg:#007bff;}, restrict the variable to only act on the component and its child elements; 2. Use fallback value to ensure that there is a default substitution when the variable is not defined, such as color:var(--text-color,#333); 3. Use nesting priority to achieve style override, such as .card.dark internal redefinition --bg and combine naming specifications to reduce the possibility of conflict, thereby improving the flexibility and stability of the style.

  • Addressing CSS Browser Compatibility issues and prefixes
    Addressing CSS Browser Compatibility issues and prefixes
    To deal with CSS browser compatibility and prefix issues, you need to understand the differences in browser support and use vendor prefixes reasonably. 1. Understand common problems such as Flexbox and Grid support, position:sticky invalid, and animation performance is different; 2. Check CanIuse confirmation feature support status; 3. Correctly use -webkit-, -moz-, -ms-, -o- and other manufacturer prefixes; 4. It is recommended to use Autoprefixer to automatically add prefixes; 5. Install PostCSS and configure browserslist to specify the target browser; 6. Automatically handle compatibility during construction; 7. Modernizr detection features can be used for old projects; 8. No need to pursue consistency of all browsers,

  • Implementing custom web fonts using @font-face css rule
    Implementing custom web fonts using @font-face css rule
    Use @font-face to load custom fonts to pay attention to syntax, format compatibility and performance optimization. 1. Correct writing methods include specifying font name, multi-format path (such as woff2, woff), setting font-weight and font-style, and using relative paths or CDN; 2. Prioritize the woff2 format, followed by woff, and the font format can be converted through tools; 3. In terms of performance, the character set and variant number should be limited, and font-display:swap should be used to avoid blank text; 4. Self-hosting can improve control and privacy protection, but it needs to handle file configuration and server MIME type support by yourself.

    Advanced CSS hover effects tutorial
    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.

  • Managing stacking contexts with CSS Z-index property
    Managing stacking contexts with CSS Z-index property
    The problem with z-index often stems from insufficient understanding of the stacked context. 1.z-index is only valid in the same stacking context, and the parent container level determines the upper limit of the child element; 2. The way to create a new stacking context includes setting non-static position, non-auto z-index, transform, filter and other properties; 3. The pop-up window is blocked, which may be because the parent container has created an independent context, and it should be mounted to a higher level; 4. When multiple components are in different contexts, the hierarchy scope must be uniformly planned and managed with CSS variables; 5. Troubleshooting problems, you can view the computed style and temporarily add visual identity to assist in judgment.

  • Implementing object-fit property for images and videos in css
    Implementing object-fit property for images and videos in css
    The object-fit property prevents deformation by controlling the scaling behavior of images and videos in the container. Its core values ??include contain (keep the proportions to the container), cover (cover and crop the excess), fill (stretch fill the container), none (keep the original size), and scale-down (take none and contain smaller ones). For images, use object-fit:cover; to ensure that images of different sizes are displayed consistently in a fixed layout; for videos, this property also applies, such as filling the container without stretching when used in video chat UI or background video. In terms of browser support, modern browsers support it, but IE11 is not compatible, polyfill or

    Techniques for vertical centering text within a container using css
    There are three ways to vertically center the text: one is to use flex layout, set display:flex and align-items:center for the container; the second is to use line-height for a single line of text, and the setting value is consistent with the container height; the third is to add transform to absolute positioning, set top and left to 50% and translate (-50%,-50%); in addition, it is necessary to note that the container must have clear height, adaptation issues of multi-line text and adjustments under responsive design.

  • Integrating Custom Fonts using CSS @font-face rule
    Integrating Custom Fonts using CSS @font-face rule
    The key to introducing custom fonts with @font-face is format selection, path accuracy and compatibility considerations; 1. First, ensure that the basic structure of @font-face is written correctly, specify the font-family and src attributes, and give priority to the use of .woff2 and .woff formats; 2. Note that the path should be relative or absolute paths, and ensure that the server can provide font files correctly; 3. In terms of compatibility, it is recommended to provide .woff2 and .woff at the same time to adapt to modern browsers. TTF/OTF can be used as backups, and EOT and SVG have been basically eliminated; 4. Common problems during use include cross-domain loading, CORS needs to be set, path errors need to be checked whether the writing is correct, and the font has not taken effect. You need to confirm that the corresponding fo is used.
