Bootstrap 4 Grid - Large

Large Grid Example

In the previous chapter, we presented a grid example with classes for small and medium devices. We used two divs (columns) and we gave them a 25%/75% split on small devices, and a 50%/50% split on medium devices:

But on large devices the design may be better as a 33%/66% split.

For large devices we will use the .col-lg-* classes:

Now Bootstrap is going to say "at the small size, look at classes with -sm- in them and use those. At the medium size, look at classes with -md- in them and use those. At the large size, look at classes with the word -lg- in them and use those".

The following example will result in a 25%/75% split on small devices, a 50%/50% split on medium devices, and a 33%/66% split on large and xlarge devices. On extra small devices, it will automatically stack (100%):

Using Only Large

In the example below, we only specify the .col-lg-6 class (without .col-md-* and/or .col-sm-*). This means that large and xlarge devices will split 50%/50%. However, for medium, small AND extra small devices, it will stack vertically (100% width):

Auto Layout Columns

In Bootstrap 4, there is an easy way to create equal width columns for all devices: just remove the number from .col-lg-* and only use the .col-lg class on a specified number of col elements. Bootstrap will recognize how many columns there are, and each column will get the same width.

If the screen size is less than 992px, the columns will stack horizontally:
