Writing Better CSS

Following CSS best practices makes your code more maintainable, performant, and professional.

Good CSS architecture prevents issues as your project grows.

• Use meaningful class names (BEM: Block__Element--Modifier)
• Organize CSS logically (base, layout, components, utilities)
• Avoid !important - use specific selectors instead
• Use CSS variables for repeated values
• Mobile-first responsive design
• Minimize use of IDs for styling
• Keep selectors short and specific
• Use shorthand properties when appropriate
• Comment your code sections
• Group related properties together
• Use consistent formatting and indentation
• Optimize for performance (avoid excessive nesting)
• Use CSS preprocessors (Sass, Less) for large projects
• Validate your CSS regularly
• Test across different browsers
