How can I ensure an image doesn\'t exceed a specific size while maintaining its aspect ratio when using 100% width or height in CSS?

Establishing Aspect Ratio Constraints for 100% Width or Height in CSS

In CSS, assigning a 100% width or height to an image preserves the aspect ratio but can result in the image being too large or too small for the desired position.

One potential solution is to place the image within a DIV and apply overflow:hidden to crop any excess. However, this will only limit the size of the image and not affect its aspect ratio.

If preserving the aspect ratio is not necessary, setting max-width and max-height properties on the image can ensure that it doesn't exceed a specific size while still preserving the aspect ratio. By setting these maximum dimensions, the image will resize accordingly to fit within the specified boundaries.

For example:

<code class="css">img {
  max-width: 200px;
  max-height: 150px;
}</code>

With this approach, the image will not expand larger than 200px in width or 150px in height, while maintaining its aspect ratio.
