In Bootstrap 3 I use this:
.something { padding: 5px; @media screen and (min-width: $screen-sm-min) { padding: 20px; } @media screen and (min-width: $screen-md-min) { padding: 40px; } }
How can I do the same thing in Boostrap 4-alpha? I can't find an example in their docs. This is in variables.scss
$grid-breakpoints: ( xs: 0, sm: 576px, md: 768px, lg: 992px, xl: 1200px ) !default; @include _assert-ascending($grid-breakpoints, "$grid-breakpoints"); @include _assert-starts-at-zero($grid-breakpoints);
Use breakpoint mixins like this:
.something { padding: 5px; @include media-breakpoint-up(sm) { padding: 20px; } @include media-breakpoint-up(md) { padding: 40px; } }
v4 breakpoints reference
v4 alpha6 breakpoints reference
Below full options and values.
Breakpoint & up (toggle on value and above):
@include media-breakpoint-up(xs) { ... } @include media-breakpoint-up(sm) { ... } @include media-breakpoint-up(md) { ... } @include media-breakpoint-up(lg) { ... } @include media-breakpoint-up(xl) { ... }
breakpoint & up values:
// Extra small devices (portrait phones, less than 576px) // No media query since this is the default in Bootstrap // Small devices (landscape phones, 576px and up) @media (min-width: 576px) { ... } // Medium devices (tablets, 768px and up) @media (min-width: 768px) { ... } // Large devices (desktops, 992px and up) @media (min-width: 992px) { ... } // Extra large devices (large desktops, 1200px and up) @media (min-width: 1200px) { ... }
breakpoint & down (toggle on value and down):
@include media-breakpoint-down(xs) { ... } @include media-breakpoint-down(sm) { ... } @include media-breakpoint-down(md) { ... } @include media-breakpoint-down(lg) { ... }
breakpoint & down values:
// Extra small devices (portrait phones, less than 576px) @media (max-width: 575px) { ... } // Small devices (landscape phones, less than 768px) @media (max-width: 767px) { ... } // Medium devices (tablets, less than 992px) @media (max-width: 991px) { ... } // Large devices (desktops, less than 1200px) @media (max-width: 1199px) { ... } // Extra large devices (large desktops) // No media query since the extra-large breakpoint has no upper bound on its width
breakpoint only:
@include media-breakpoint-only(xs) { ... } @include media-breakpoint-only(sm) { ... } @include media-breakpoint-only(md) { ... } @include media-breakpoint-only(lg) { ... } @include media-breakpoint-only(xl) { ... }
breakpoint only values (toggle in between values only):
// Extra small devices (portrait phones, less than 576px) @media (max-width: 575px) { ... } // Small devices (landscape phones, 576px and up) @media (min-width: 576px) and (max-width: 767px) { ... } // Medium devices (tablets, 768px and up) @media (min-width: 768px) and (max-width: 991px) { ... } // Large devices (desktops, 992px and up) @media (min-width: 992px) and (max-width: 1199px) { ... } // Extra large devices (large desktops, 1200px and up) @media (min-width: 1200px) { ... }
I answered a similar question here
As @Syden said, the mixins will work. Another option is using SASS map-get like this..
@media (min-width: map-get($grid-breakpoints, sm)){ .something { padding: 10px; } } @media (min-width: map-get($grid-breakpoints, md)){ .something { padding: 20px; } }
