Understanding Bulma's Grid System

Bulma uses a Flexbox-based grid system with columns. The grid is built using the .columns and .column classes.

Example: Basic Grid Layout

<div class="columns">
  <div class="column">First column</div>

  <div class="column">Third column</div>

</div>

Example: Responsive Columns

<div class="columns">
  <div class="column is-half">Half width</div>
  <div class="column is-one-quarter">One quarter</div>
  <div class="column is-one-quarter">One quarter</div>
</div>
