Level

The Bulma includes horizontal level to specify the level for left side and right side. The level-left class specifies element at left side and level-right class specifies element at right side. You can define the each individual element by using level-item class.

Level contains two types of levels.

Centered Level − You can make the items center in the level container.
Mobile Level − If you want to display the items horizontally on mobile, then use is-mobile modifier in the level container.

Let’s create a simple example for level by using the above level types as shown below −
