CSS Tricks


Just found two neat css tricks:
- Force image resize and keep aspect ratio [1]
- Absolute horizontal and vertical centering [2]

Force image resize and keep aspect ratio

Sometime we want to scale images to fit them into avaiable space, e.g. a photo in friendica's stream. We can easly set a maximum width and the image will scale correctly:
.image { max-width: 100px; }
If image width is > 100px, the browser will scale the width to 100px and the height to whatever is in relation to image ratio.
So, if the image is 400x200, the browser will scale it to 100x50.

But.

What if the image is 400x1200?
The browser will do his job and will show it ad 100x600. that could be quite tall..

The first thing we try is to add max-height:.image { max-width: 100px; max-height:100px... show more
