For faster mobile-friendly and responsive development, Bootstrap includes dozens of utility classes for showing, hiding, aligning, and spacing content.
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
Bootstrap 4 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. Most
of our components are built with flexbox enabled.
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. Bootstrap 4 includes a five-level
scale for spacing utilities, based on a
1rem
value default
$spacer
variable. Choose values for all viewports (e.g.,
.mr-3
for
margin-right: 1rem
), or pick responsive variants to target specific viewports (e.g.,
.mr-md-3
for
margin-right: 1rem
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.
