Modifiers syntax

Most Bulma elements have alternative styles. To apply them, you only need to append one of the modifier classes. They all start with is- or has-.

Let's start with a simple button that uses the "button" CSS class:

<a class="button">
  Button
</a>

By adding the "is-primary" CSS class, you can modify the color:

<a class="button is-primary">
  Button
</a>

You can use one of the 6 main colors:

  • is-primary
  • is-link
  • is-info
  • is-success
  • is-warning
  • is-danger
<a class="button is-primary">
  Button
</a>
<a class="button is-link">
  Button
</a>
<a class="button is-info">
  Button
</a>
<a class="button is-success">
  Button
</a>
<a class="button is-warning">
  Button
</a>
<a class="button is-danger">
  Button
</a>

You can also alter the size:

  • is-small
  • is-medium
  • is-large
<a class="button is-small">
  Button
</a>
<a class="button">
  Button
</a>
<a class="button is-medium">
  Button
</a>
<a class="button is-large">
  Button
</a>

Or the style or state:

  • is-outlined
  • is-loading
  • [disabled]
<a class="button is-primary is-outlined">
  Button
</a>
<a class="button is-loading">
  Button
</a>
<a class="button" disabled>
  Button
</a>
As a result, it's very easy to combine modifiers:
<a class="button is-primary is-small" disabled>
  Button
</a>
<a class="button is-info is-loading">
  Button
</a>
<a class="button is-danger is-outlined is-large">
  Button
</a>
