在 Bootstrap 3 中我使用这个:
.something {
padding: 5px;
@media screen and (min-width: $screen-sm-min) {
padding: 20px;
}
@media screen and (min-width: $screen-md-min) {
padding: 40px;
}
}
我如何在 Boostrap 4-alpha 中做同样的事情?我在他们的文档中找不到示例。 这是在variables.scss中
$grid-breakpoints: (
xs: 0,
sm: 576px,
md: 768px,
lg: 992px,
xl: 1200px
) !default;
@include _assert-ascending($grid-breakpoints, "$grid-breakpoints");
@include _assert-starts-at-zero($grid-breakpoints);
最佳答案
更新:Bootstrap 5。
v5 breakpoints reference (latest)
<小时/>原始答案 - Bootstrap v4:使用断点混合,如下所示:
.something {
padding: 5px;
@include media-breakpoint-up(sm) {
padding: 20px;
}
@include media-breakpoint-up(md) {
padding: 40px;
}
}
v4 alpha6 breakpoints reference
<小时/>低于完整选项和值。
断点及向上(在值及以上之间切换):
@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) { ... }
断点和上限值:
// 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(在值和向下之间切换):
@include media-breakpoint-down(xs) { ... }
@include media-breakpoint-down(sm) { ... }
@include media-breakpoint-down(md) { ... }
@include media-breakpoint-down(lg) { ... }
断点和下降值:
// 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) { ... }
