# Aspect Ratio

The Aspect Ratio utility uses the native CSS aspect-ratio property to maintain consistent proportions for elements. Perfect for images, videos, and containers that need to maintain specific width-to-height ratios across different screen sizes.

### Basic Usage

Use predefined aspect ratio classes to constrain element dimensions to specific proportions.
 These utilities apply the CSS `aspect-ratio` property directly to elements.

1:1

16:9

3:4
