  • Achieving perfect horizontal and vertical centering using CSS
    Achieving perfect horizontal and vertical centering using CSS
    Using Flexbox, absolute positioning combined with transform or Grid layout are the three main ways to achieve horizontal and vertical centering of elements. First, Flexbox can quickly center elements by setting the container to flex layout and using justify-content and align-items attributes; second, absolute positioning combined with transform attributes is suitable for modal boxes or prompt boxes, and then centering is achieved by setting top and left to 50% and then transferring (-50%,-50%) backwards; third, CSSGrid can complete centering through a line of place-items:center code, and can also control the alignment method separately. These three methods are suitable for each

  • Solving vertical alignment challenges with CSS methods
    Solving vertical alignment challenges with CSS methods
    There are three common methods to achieve vertical centering: 1. Use Flexbox to achieve centering by setting the display:flex, align-items and justify-content attributes of the container, which is suitable for most block-level layouts; 2. Use Grid layout, and implement two-dimensional centering through the display:grid and place-items attributes, which is suitable for complex layout scenarios; 3. Use absolute positioning transform to achieve independent element centering by positioning the center point of the element and reverse offset, which does not depend on the container type. When choosing, trade-offs should be made based on project requirements and browser compatibility, and avoid using mobile devices that support poor table-cell methods.

  • Using flexbox for complex css layouts
    Using flexbox for complex css layouts
    To use flexbox to implement a responsive navigation bar, first set .navbar as a flex container, and use justify-content:space-between to achieve spindle alignment; secondly add flex-wrap:wrap to allow navigation items to automatically wrap when there is insufficient space; finally control the spacing between items through the gap attribute. In addition, when building a card layout, 1. Set the parent container to display:flex; 2. Use flex-basis to control the width of the child item, such as the three-column layout can be calc (33.33%-gap); 3. Dynamically adjust flex-basis to adapt to different screens in combination with media queries. Note when using nested flex containers

  • Implementing CSS Flexbox item wrapping
    Implementing CSS Flexbox item wrapping
    To make the items in the Flexbox layout automatically wrap, you need to set flex-wrap:wrap; 1. Use the flex-wrap attribute to control whether to wrap the line. Common values ??include nowrap (not wrapping), wrap (down wrapping) and wrap-reverse (up wrapping); 2. Combining the flex-direction attribute can change the direction of the spindle, affecting the arrangement order and line breaking position, such as row (default from left to right), row-reverse (from right to left), column (from top to bottom), etc.; 3. After wrapping, it is recommended to use the gap attribute to set the project spacing uniformly to improve the layout neatness, but pay attention to browser compatibility.

  • Creating dropdown menus with pure css
    Creating dropdown menus with pure css
    The key to making a pure CSS drop-down menu is that it has clear structure, natural interaction, and no JavaScript is required. 1. Use unordered lists and list items to build a semantic HTML structure. Place the main menu item under .menu, and the submenu is implemented with nesting; 2. Display hidden through CSS's :hover pseudo-class and positioning control. Use display:none; hide submenu by default. Use display:block; to display when hovering, and set position:absolute; to coordinate with parent element position:relative; to coordinate positioning; 3. Optimize the experience and add transition animations, such as opacity and visibility combined with transition implementation.

    Using CSS `will-change` for performance hints
    will-change is a tool that prompts browsers that some elements may change, but is not a performance magic wand. The following points should be followed when using: 1. Use only when expected to change frequently or complexly, such as transform, opacity or filter; 2. Add before the animation starts and remove after it ends; 3. Avoid global or premature application; 4. Do not abuse or retain for a long time; 5. Use performance debugging tools to judge the effect.

  • Demystifying CSS Units: px, em, rem, vw, vh comparisons
    Demystifying CSS Units: px, em, rem, vw, vh comparisons
    The choice of CSS units depends on design requirements and responsive requirements. 1.px is used for fixed size, suitable for precise control but lack of elasticity; 2.em is a relative unit, which is easily caused by the influence of the parent element, while rem is more stable based on the root element and is suitable for global scaling; 3.vw/vh is based on the viewport size, suitable for responsive design, but attention should be paid to the performance under extreme screens; 4. When choosing, it should be determined based on whether responsive adjustments, element hierarchy relationships and viewport dependence. Reasonable use can improve layout flexibility and maintenance.

  • Styling SVG elements using css
