Because images can take a few seconds to load (or not at all), use the .image container to specify a precisely sized container so that your layout isn't broken because of image loading or image errors.
Images
A container for responsive images
Fixed square images
There are 7 dimensions to choose from, useful for avatars:
image is-16x16 |
16x16px | |
image is-24x24 |
24x24px | |
image is-32x32 |
32x32px | |
image is-48x48 |
48x48px | |
image is-64x64 |
64x64px | |
image is-96x96 |
96x96px | |
image is-128x128 |
128x128px |
Retina images
Because the image is fixed in size, you can use an image that is twice as big. So for example, in a 128x128 container, you can use a 256x256 image, but resized to 128x128 pixels.
Responsive images with ratios
If you don't know the exact dimensions but know the ratio instead, you can use one of the 5 ratio modifers:
image is-square |
Square (or 1by1) | |
image is-1by1 |
1 by 1 | |
image is-4by3 |
4 by 3 | |
image is-3by2 |
3 by 2 | |
image is-16by9 |
16 by 9 | |
image is-2by1 |
2 by 1 |
The .image container will take up the whole width while maintaining the perfect ratio.
