Headlines

The headlines utility provides CSS classes for responsive heading sizes, allowing you to control headline appearance across breakpoints.

Skip to:

Class naming convention

Classes use the format {prefix}-headline-{size}--{breakpoint}.

Element Description
prefix Always oc for OTTO Components
size One of 10, 25, 50, 100, 200, 300, 400
breakpoint Optional, one of s, m, l, xl, xxl (applies styles from the breakpoint upwards)

Usage guidelines

To use the headline utility, add the appropriate CSS class to your heading elements. For example, to set the headline size to 100 from the m breakpoint and up, use the oc-headline-100--m class:

<h1 class="oc-headline-100--m">This is a headline using size 100 from medium screens and up.</h1>

Use the controls in the interactive headline demo to see these classes in action.
