Utilities for layout
For faster mobile-friendly and responsive development, OUDS Web includes dozens of utility classes for showing, hiding, aligning, and spacing content.
On this page
Changing display
Use our display utilities for responsively toggling common values of the display property. Mix it with our grid system, content, or components to show or hide them across specific viewports.
Flexbox options
OUDS Web is built with flexbox, but not every element’s display has been changed to display: flex as this would add many unnecessary overrides and unexpectedly change key browser behaviors.
Should you need to add display: flex to an element, do so with .d-flex or one of the responsive variants (e.g., .d-sm-flex). You’ll need this class or display value to allow the use of our extra flexbox utilities for sizing, alignment, spacing, and more.
Margin and padding
Use the margin and padding spacing utilities to control how elements and components are spaced and sized. OUDS Web includes an eleven-level scale for spacing utilities, based on a 4px value default $ouds-dimension-base variable. Choose values for all viewports (e.g., .me-tall for margin-right: 16px in LTR), or pick responsive variants to target specific viewports (e.g., .me-md-tall for margin-right: 16px —in LTR— starting at the md breakpoint).
Toggle visibility
When toggling display isn’t needed, you can toggle the visibility of an element with our visibility utilities. Invisible elements will still affect the layout of the page, but are visually hidden from visitors.
