v5断点参考
原始答案:像这样使用断点混合:
.something {

padding: 20px;
}
@include media-breakpoint-up(md) {
padding: 40px;
}
}

v4 alpha6断点参考
低于完整的选项和值。
断点和向上(切换值及以上):
@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) { ... }
断点和向上值:
// 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) { ... }
断点和向下(切换值和向下):
@include media-breakpoint-down(xs) { ... }
@include media-breakpoint-down(sm) { ... }
@include media-breakpoint-down(md) { ... }
@include media-breakpoint-down(lg) { ... }
断点和向下值:
// 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
仅断点:
@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) { ... }
仅断点值(仅在值之间切换):
// 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) { ... }
