CSS Code Formatting Best Practices
Writing clean, readable, and well-structured CSS improves maintainability, collaboration, and ensures consistent styling across projects.
1. Consistent Indentation
Maintain uniform indentation to improve readability:
- Use 2 spaces per level consistently.
- Avoid mixing tabs and spaces.
- Indent nested selectors, media queries, and rule sets properly.
2. Organize Properties Logically
Group related CSS properties together:
- Example: box model properties (margin, padding, border) together.
- Follow a consistent order across stylesheets.
- Makes it easier to read and maintain rules.
3. Limit Selector Nesting
Keep selectors shallow for clarity and maintainability:
- Avoid deeply nested rules that are hard to read.
- Use classes and IDs efficiently instead of long selector chains.
- Helps prevent specificity issues.
4. Use Meaningful Class Names
Choose descriptive and consistent names for CSS classes:
- Use lowercase and hyphen-separated names.
- Avoid generic names like
boxoritem. - Reflect component purpose, not styling.
5. Maintain Consistent Spacing
Use consistent spacing around braces, colons, and semicolons:
- Example:
color: red;with spaces after colon. - Separate rule sets with blank lines for readability.
- Consistent formatting improves maintainability.
6. Follow Community Conventions
Adhere to established CSS conventions and style guides:
- Follow conventions like Airbnb or Google CSS style guides.
- Use formatters like Prettier or stylelint for consistent output.
- Helps teams maintain uniform CSS stylesheets.
Before Formatting
header{background:#333;color:#fff;padding:20px;text-align:center}header h1{margin:0;font-size:2rem}nav ul{list-style:none;padding:0;display:flex;justify-content:center}nav ul li{margin:0 10px}nav ul li a{text-decoration:none;color:#fff;font-weight:bold}
After Formatting
header {
background: #333;
color: #fff;
padding: 20px;
text-align: center;
}
header h1 {
margin: 0;
font-size: 2rem;
}
nav ul {
list-style: none;
padding: 0;
display: flex;
justify-content: center;
}
nav ul li {
margin: 0 10px;
}
nav ul li a {
text-decoration: none;
color: #fff;
font-weight: bold;
}
