Consider a <card></card> component. It shouldn't be directly adjacent to other components without spacing. This applies to almost every component. So, how should component spacing be managed within a design system?
Should spacing be applied directly to the <card></card> using margins (e.g., margin-block-end: 1rem; margin-inline-end: 1rem;)? This is problematic because it assumes the context of the card's placement. What if the card is nested within a <grid></grid> component that already uses gap: 1rem? This creates conflicts and hard-coded spacing values.
Approaches to Component Spacing
Several approaches exist, each with trade-offs:
- Baked-in Spacing: Incorporating spacing directly into each component. This is restrictive and inflexible.
-
Spacing Props: Passing spacing values as props (e.g.,
<card space="xxl"></card>). This can become verbose, potentially requiring multiple props for different directions. -
Dedicated Spacing Components: Using components like
<spacer></spacer>or<layout></layout>solely for spacing. This cleanly separates concerns but can add unnecessary DOM elements and complexity.
The optimal solution is a matter of debate. While some advocate for eliminating margins entirely, a more pragmatic approach is to separate layout and spacing concerns from the core component functionality. Content components should be agnostic to their placement, allowing higher-level layout mechanisms to handle spacing.
The increasing adoption of gap in Flexbox and Grid suggests a shift away from relying solely on margins. This trend aligns with the desire for more declarative and maintainable layouts.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

What is Autoprefixer and how does it work?
Jul 02, 2025 am 01:15 AM
Autoprefixer is a tool that automatically adds vendor prefixes to CSS attributes based on the target browser scope. 1. It solves the problem of manually maintaining prefixes with errors; 2. Work through the PostCSS plug-in form, parse CSS, analyze attributes that need to be prefixed, and generate code according to configuration; 3. The usage steps include installing plug-ins, setting browserslist, and enabling them in the build process; 4. Notes include not manually adding prefixes, keeping configuration updates, prefixes not all attributes, and it is recommended to use them with the preprocessor.

CSS: When Does Case Matter (and When Doesn't)?
Jun 19, 2025 am 12:27 AM
In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
