Writing maintainable CSS doesn't have to be complicated. Here are some quick tips that will improve your stylesheets immediately.

Use Custom Properties

CSS custom properties (variables) let you define reusable values. Use them for colors, spacing, and typography to keep your styles consistent and easy to update.

Embrace Logical Properties

Instead of margin-left and margin-right, use margin-inline. This makes your CSS work better with different writing directions and is more future-proof.

• margin-inline instead of margin-left/right
• padding-block instead of padding-top/bottom
• inset-inline instead of left/right

Keep Specificity Low

Prefer classes over IDs and avoid nesting too deeply. Low specificity makes styles easier to override and maintain. When in doubt, keep it simple.
