jul*_*ert 11 css border media-queries responsive-design bootstrap-4
我正在使用引导程序创建一个移动优先的响应式布局,并设置了各种行和列,我可以针对不同类别的屏幕尺寸进行调整。
我想知道是否有纯引导样式类可以让我应用和删除不同大小的边框,而不必创建我自己的 css 媒体查询。
例如,如果我只想在行中的第一列以中等大小浮动时才在第一列上有一个边框右侧...我知道这不是真正的代码,但是是否有与我相同的影响哑巴找?
<div class="row">
<div class="col-12 col-md-6 border border-top-0 border-right-0 border-bottom-0 border-left-0 border-md-right-1">
<p>Lorem ipsum</p>
</div>
<div class="col-12 col-md-6">
<p>Dolor sit amet</p>
</div>
</div>

我也在使用 maxcdn css,所以无法进入 sass。有什么建议?

Bootstrap 不支持开箱即用的响应式边框。您可以按照此处的说明获取引导程序中的响应式边框 - https://github.com/twbs/bootstrap/issues/23892#issuecomment-378172751
这是代码:
@each $breakpoint in map-keys($grid-breakpoints) {
@include media-breakpoint-up($breakpoint) {
$infix: breakpoint-infix($breakpoint, $grid-breakpoints);
.border#{$infix}-top { border-top: $border-width solid $border-color !important; }
.border#{$infix}-right { border-right: $border-width solid $border-color !important; }
.border#{$infix}-bottom { border-bottom: $border-width solid $border-color !important; }
.border#{$infix}-left { border-left: $border-width solid $border-color !important; }
.border#{$infix}-top-0 { border-top: 0 !important; }
.border#{$infix}-right-0 { border-right: 0 !important; }
.border#{$infix}-bottom-0 { border-bottom: 0 !important; }
.border#{$infix}-left-0 { border-left: 0 !important; }
.border#{$infix}-x {
border-left: $border-width solid $border-color !important;
border-right: $border-width solid $border-color !important;
}
.border#{$infix}-y {
border-top: $border-width solid $border-color !important;
border-bottom: $border-width solid $border-color !important;
}
}

没有人支持它。但是添加自己的代码将修复它。根据@sharan 的回答(谢谢!),如果您想一次定义所有边框,我已经进行了一些修改。原文:https : //stackoverflow.com/a/57089704/5677177

在 Bootstrap5 中,您可以修改实用程序: https://getbootstrap.com/docs/5.1/utilities/api/#enable-responsive
@import "bootstrap/scss/functions";
@import "bootstrap/scss/variables";
@import "bootstrap/scss/utilities";
$utilities: map-merge(
$utilities,
(
"border": map-merge(
map-get($utilities, "border"),
( responsive: true ),
),
"border-top": map-merge(
map-get($utilities, "border-top"),
( responsive: true ),
),
"border-end": map-merge(
map-get($utilities, "border-end"),
( responsive: true ),
),
"border-bottom": map-merge(
map-get($utilities, "border-bottom"),
( responsive: true ),
),
"border-start": map-merge(
map-get($utilities, "border-start"),
( responsive: true ),
),
)
);

编译后的 CSS 将会是这样的:
.border-sm {
border: 1px solid #e9ecef !important;
}
.border-sm-0 {
border: 0 !important;
}
.border-top-sm {
border-top: 1px solid #e9ecef !important;
}
.border-top-sm-0 {
border-top: 0 !important;
}
.border-end-sm {
border-right: 1px solid #e9ecef !important;
}
.border-end-sm-0 {
border-right: 0 !important;
}
.border-bottom-sm {
border-bottom: 1px solid #e9ecef !important;
}
.border-bottom-sm-0 {
border-bottom: 0 !important;
}
.border-start-sm {
border-left: 1px solid #e9ecef !important;
}
.border-start-sm-0 {
border-left: 0 !important;
}
