The AspectRatio component is used to maintain a specific aspect ratio for its children. This is particularly useful for responsive designs where you want to ensure that an element retains its proportions regardless of the screen size.
## Component Structure
```rust
AspectRatio {
// The aspect ratio to maintain (width / height)
ratio: 4. / 3.,
// The children of the AspectRatio component will be rendered within it.
{children}
}
```
