Bootstrap 4  Display Utility Classes for Hiding and Showing Elements

To hide elements we will use the .d-none class or one of the .d-{sm,md,lg,xl}-none classes for any responsive screen variation.

To show an element only on a given interval of screen sizes you can combine one .d-*-none class with a .d-*-* class, for example .d-none .d-md-block .d-xl-none will hide the element for all screen sizes except on medium and large devices.

xs (No media query – default) sm (<576px) md (<768px) lg (≥992px) xl (≥1200px)
hidden only on .d-none .d-sm-block .d-sm-none .d-md-block .d-md-none .d-lg-block .d-lg-none .d-xl-block .d-xl-none
visible only on .d-block .d-sm-none .d-none .d-sm-block .d-md-none .d-none .d-md-block .d-lg-none .d-none .d-lg-block .d-xl-none .d-none .d-xl-block
hidden on +larger .d-sm-none .d-md-none .d-lg-none .d-xl-none .d-none
hidden on +smaller .d-none (never) .d-block .d-sm-none .d-block .d-md-none .d-block .d-lg-none .d-block .d-xl-none
Hidden on all .d-none .d-none .d-none .d-none .d-none
Visible on all .d-block .d-block .d-block .d-block .d-block

Exanple

<div class=”d-none d-sm-block”>This div is showing on md+</div>
<div class=”d-sm-none”>This div showing on small screens</div>

Converting Bootstrap 3 Classes to Bootstrap 4

Update for Bootstrap 4 (2018)

The hidden-* and visible-* classes no longer exist in Bootstrap 4. If you want to hide an element on specific tiers or breakpoints in Bootstrap 4, use the d-* display classes accordingly.

Remember that extra-small/mobile (formerly xs) is the default (implied) breakpoint, unless overridden by a larger breakpoint. Therefore, the -xs infix no longer exists in Bootstrap 4.

Show/hide for breakpoint and down:

hidden-xs-down (hidden-xs) = d-none d-sm-block
hidden-sm-down (hidden-sm hidden-xs) = d-none d-md-block
hidden-md-down (hidden-md hidden-sm hidden-xs) = d-none d-lg-block
hidden-lg-down = d-none d-xl-block
hidden-xl-down (n/a 3.x) = d-none (same as hidden)
Show/hide for breakpoint and up:

hidden-xs-up = d-none (same as hidden)
hidden-sm-up = d-sm-none
hidden-md-up = d-md-none
hidden-lg-up = d-lg-none
hidden-xl-up (n/a 3.x) = d-xl-none
Show/hide only for a single breakpoint:

hidden-xs (only) = d-none d-sm-block (same as hidden-xs-down)
hidden-sm (only) = d-block d-sm-none d-md-block
hidden-md (only) = d-block d-md-none d-lg-block
hidden-lg (only) = d-block d-lg-none d-xl-block
hidden-xl (n/a 3.x) = d-block d-xl-none
visible-xs (only) = d-block d-sm-none
visible-sm (only) = d-none d-sm-block d-md-none
visible-md (only) = d-none d-md-block d-lg-none
visible-lg (only) = d-none d-lg-block d-xl-none
visible-xl (n/a 3.x) = d-none d-xl-block
Demo of the responsive display classes in Bootstrap 4

Also, note that d-*-block can be replaced with d-*-inline, d-*-flex, d-*-table-cell, d-*-table etc.. depending on the display type of the element.
