  • Using css transforms for rotations, scaling, and skewing
    Using css transforms for rotations, scaling, and skewing
    The CSStransform property implements rotation, scale and tilt effects through the rotate, scale and skew functions. 1.rotate() is used to rotate elements, which can specify the angle and adjust the rotation center with transform-origin; 2.scale() controls scaling, supports unified scaling or sets scaleX and scaleY respectively, without affecting the layout position; 3.skew() implements tilt, which is often used in combination with other functions to enhance visual effects, but excessive use should be avoided to affect readability and page stability.

  • How to select the first and last child element with CSS Selectors?
    How to select the first and last child element with CSS Selectors?
    The key to using CSS to select the first and last child elements is to understand the usage of pseudo-class selectors. :first-child selects the first child element under the parent element and the label matches, such as li:first-child acts on the first; :last-child selects the last child element and the label matches, such as li:last-child acts on the last; if you only want to match the first or last element of the same type, you should use :first-of-type or :last-of-type. Common errors include structural nested interference and HTML inconsistency that cause selector failure, such as when incorporating other tags: first-child may not hit the target. Master this

  • How to write a media query for high-resolution (Retina) displays?
    How to write a media query for high-resolution (Retina) displays?
    To write practical and reliable media query rules, you must first use min-resolution or -webkit-min-device-pixel-ratio to determine the device resolution, then load high-definition pictures through background image replacement or img's srcset, then optimize the display effect of SVG and icon fonts, and pay attention to adapting to mainstream devices, testing and verification and performance optimization. The specific steps are as follows: 1. Use min-resolution:2dppx or -webkit-min-device-pixel-ratio:2 to detect the Retina screen; 2. Use media query to switch the background image to the HD version or use the srcset attribute of img to automatically load the adapter

  • Controlling flex item wrapping behavior with css flex-wrap
    Controlling flex item wrapping behavior with css flex-wrap
    flex-wrap controls the line wrapping behavior of child elements of elastic containers. It has three values: nowrap (there is no line break by default), wrap (the line break is allowed, the direction is from top to bottom, left to right), wrap-reverse (the line break is allowed, the direction is from bottom to top). If the project does not wrap the line as expected, it may be due to the project width being too small or too large and the container width being undefined. It can be adjusted by min-width, percentage width or flex-grow respectively. After a row-gap and column spacing can be set through row-gap and column-gap. wrap-reverse is often used in special layouts such as bottom alignment or reverse arrangement. Use flex-wrap reasonably to combine width and spacing settings to achieve flexible layout effects

  • Mastering CSS Grid Layout for complex interfaces
    Mastering CSS Grid Layout for complex interfaces
    CSSGrid is one of the strongest tools for handling complex interface layouts. It supports a two-dimensional grid system that can control rows and columns at the same time. After defining the container with display:grid, set the row and column size through grid-template-columns and grid-template-rows, and 1fr represents a copy of the available space. Common techniques include: 1. Use repeat() to simplify the definition of repeated rows and columns; 2. Use minmax() to set the content adaptive range; 3. Improve readability and simplify structure maintenance through grid-template-areas named areas; 4. Use gap to set the spacing uniformly; 5. Use auto-fit to realize responsive automatic wrapping

    Exploring CSS Module patterns for component-based styling
    CSSModules solves the problem of style conflict in component UI and improves maintainability through default local scope. The naming specification should clearly correspond to components such as ComponentName.module.css, use concrete class names such as .primaryButton to avoid confusion; use compose to reuse basic styles to maintain code DRY; use classnames to manage conditional class names in combination with React dynamic logic; use:global() to define global styles but avoid abuse. These steps ensure efficient expansion and maintenance.

  • Using css blend modes for creative image effects
    Using css blend modes for creative image effects
    CSS hybrid mode realizes creative image effects through mix-blend-mode and background-blend-mode properties. 1. Mix-blend-mode controls the mixing of elements and background, such as using the difference value to allow text to penetrate the picture to display; 2. Background-blend-mode controls the mixing of background layers, such as overlaying gradient tones; 3. Pay attention to browser compatibility when using it. Safari and Chrome support is good, but IE does not support it; 4. Use the isolation attribute to avoid hierarchical interference and ensure that the parent container has content support for the mixing effect.

You can set the display method of each image with background-repeat, background-position and other attributes, and keep the order one by one; 4. Common combinations include controlling repetition, position, size and mixing mode; 5. Pay attention to compatibility when using (not supported by IE8 and earlier versions), and

  • Writing effective media queries for responsive css design
    Writing effective media queries for responsive css design
    To write responsive CSS media queries, the key is to set breakpoints around the content and adopt a mobile-first strategy. 1. You should not blindly use common breakpoints such as 768px and 992px, but should determine breakpoints based on when the content layout becomes crowded; 2. It is recommended to adopt the mobile priority principle, first define the mobile style, and then adapt it upwardly through min-width to avoid loading unnecessary resources; 3. Media queries are not limited to screen width, but can also be judged based on characteristics such as resolution, horizontal and vertical screens, dark modes, etc., but it should be avoided overcomplexity; 4. In practice, the number of breakpoints should be controlled within 3 to 5, unified naming variables are convenient for collaboration, and it is necessary to test on real devices; 5. Finally, don’t forget to add viewport meta tags to HTML to confirm

  • Understanding CSS Selector Specificity rules and cascading
    Understanding CSS Selector Specificity rules and cascading
    CSS selector priority and cascade rules determine the final application effect when multiple styles conflict. 1. The priority is determined by the selector type calculation score, inline style > ID selector > Class/Property/Pseudo-Class Selector > Element/Pseudo-Element Selector; 2. Cascading involves the priority of the style source, including user agent style, user style, developer style, !important declaration and inline style; 3. The last loaded style under the same priority covers the front; 4. Use browser developer tools to troubleshoot style conflicts, check the overlay, !important usage, spelling errors and introduction order. Mastering these rules can help write stable and clear CSS code.
