# better-tailwindcss/enforce-shorthand-classes
This rule identifies when multiple longhand Tailwind CSS classes can be replaced with a single shorthand class, improving code readability and reducing bundle size.
> [!NOTE]
> This rule might interfere with [`better-tailwindcss/enforce-canonical-classes`](./enforce-canonical-classes.md) if both rules are enabled. It is recommended to use only one of them to avoid conflicting fixes.
