Using IDs Instead of Classes: Avoid using IDs in CSS and use classes instead as IDs are harder to override.
Forgetting the Box Model: Remember to consider the box model when adding padding or borders to elements to avoid unexpected layouts. Use the 'box-sizing: border-box;' property for simplified calculations.
Overusing !important: Avoid using '!important' too frequently and improve your selector strategy to maintain better control and organization in your CSS code.
Not Using Browser DevTools: Utilize browser DevTools for debugging and troubleshooting CSS issues more efficiently.
