我想在我正在构建的页面上有5个相等的列,我似乎无法理解5列网格在这里是如何使用的: http://web.archive.org/web/20120416024539/http://domain7.com/mobile/tools/bootstrap/responsive
上面演示的五列网格是twitter引导框架的一部分吗?

当前回答
使用5个div,类为span2,并给第一个类为offset1。
<div class="row-fluid">
<div class="span2 offset1"></div>
<div class="span2"></div>
<div class="span2"></div>
<div class="span2"></div>
<div class="span2"></div>
</div>
瞧! 五列等距居中。
在引导3.0中,这段代码看起来像
<div class="row">
<div class="col-md-2 col-md-offset-1"></div>
<div class="col-md-2"></div>
<div class="col-md-2"></div>
<div class="col-md-2"></div>
<div class="col-md-2"></div>
</div>
更新
因为bootstrap 4.0默认使用Flexbox:
<div class="row">
<div class="col"></div>
<div class="col"></div>
<div class="col"></div>
<div class="col"></div>
<div class="col"></div>
</div>

我已经为任意数量的列创建了基于bootstrap定义的SASS mixin定义(个人而言,除了12列,我使用8、10和24列):
// Extended bootstrap grid system
//
// Framework grid generation
//
// Based on Bootstrap 'bootstrap/_grid-framework.scss'. Generates classes in form of `.col-(size)-x-num` of width x/num.
@mixin make-extended-grid-columns($num-columns, $i: 1, $list: ".col-xs-#{$i}-#{$num-columns}, .col-sm-#{$i}-#{$num-columns}, .col-md-#{$i}-#{$num-columns}, .col-lg-#{$i}-#{$num-columns}") {
@for $i from (1 + 1) through $num-columns {
$list: "#{$list}, .col-xs-#{$i}-#{$num-columns}, .col-sm-#{$i}-#{$num-columns}, .col-md-#{$i}-#{$num-columns}, .col-lg-#{$i}-#{$num-columns}";
}
#{$list} {
position: relative;
min-height: 1px;
padding-left: ($grid-gutter-width / 2);
padding-right: ($grid-gutter-width / 2);
}
}
@mixin float-extended-grid-columns($class, $num-columns, $i: 1, $list: ".col-#{$class}-#{$i}-#{$num-columns}") {
@for $i from (1 + 1) through $num-columns {
$list: "#{$list}, .col-#{$class}-#{$i}-#{$num-columns}";
}
#{$list} {
float: left;
}
}
@mixin calc-extended-grid-column($index, $num-columns, $class, $type) {
@if ($type == width) and ($index > 0) {
.col-#{$class}-#{$index}-#{$num-columns} {
width: percentage(($index / $num-columns));
}
}
@if ($type == push) and ($index > 0) {
.col-#{$class}-push-#{$index}-#{$num-columns} {
left: percentage(($index / $num-columns));
}
}
@if ($type == pull) and ($index > 0) {
.col-#{$class}-pull-#{$index}-#{$num-columns} {
right: percentage(($index / $num-columns));
}
}
@if ($type == offset) and ($index > 0) {
.col-#{$class}-offset-#{$index}-#{$num-columns} {
margin-left: percentage(($index / $num-columns));
}
}
}
@mixin loop-extended-grid-columns($num-columns, $class, $type) {
@for $i from 1 through $num-columns - 1 {
@include calc-extended-grid-column($i, $num-columns, $class, $type);
}
}
@mixin make-extended-grid($class, $num-columns) {
@include float-extended-grid-columns($class, $num-columns);
@include loop-extended-grid-columns($num-columns, $class, width);
@include loop-extended-grid-columns($num-columns, $class, pull);
@include loop-extended-grid-columns($num-columns, $class, push);
@include loop-extended-grid-columns($num-columns, $class, offset);
}
你可以简单地创建类:
$possible-number-extended-grid-columns: 8, 10, 24;
@each $num-columns in $possible-number-extended-grid-columns {
// Columns
@include make-extended-grid-columns($num-columns);
// Extra small grid
@include make-extended-grid(xs, $num-columns);
// Small grid
@media (min-width: $screen-sm-min) {
@include make-extended-grid(sm, $num-columns);
}
// Medium grid
@media (min-width: $screen-md-min) {
@include make-extended-grid(md, $num-columns);
}
// Large grid
@media (min-width: $screen-lg-min) {
@include make-extended-grid(lg, $num-columns);
}
}
我希望有人会觉得它有用
五列显然不是bootstrap设计的一部分。
但是对于Bootstrap v4 (alpha),有两件事可以帮助处理复杂的网格布局
Flex (http://v4-alpha.getbootstrap.com/getting-started/flexbox/),新的元素类型(官方- https://www.w3.org/TR/css-flexbox-1/) 响应式实用程序(http://v4-alpha.getbootstrap.com/layout/responsive-utilities/)
简单来说,我在用
<style>
.flexc { display: flex; align-items: center; padding: 0; justify-content: center; }
.flexc a { display: block; flex: auto; text-align: center; flex-basis: 0; }
</style>
<div class="container flexc hidden-sm-down">
<!-- content to show in MD and larger viewport -->
<a href="#">Link/Col 1</a>
<a href="#">Link/Col 2</a>
<a href="#">Link/Col 3</a>
<a href="#">Link/Col 4</a>
<a href="#">Link/Col 5</a>
</div>
<div class="container hidden-md-up">
<!-- content to show in SM and smaller viewport, I don't think 5 cols in smaller viewport are gonna be alright :) -->
</div>
不管是5 7 9 11 13还是其他概率,都没问题。 我非常确定12网格标准能够服务于90%以上的用例——所以让我们以这种方式设计——也更容易开发!
flex教程在这里“https://css-tricks.com/snippets/css/a-guide-to-flexbox/”
.col-half-offset{
margin-left:4.166666667% !important;
float: left;
}
<div className="row1 marginTop20">
<div className="col-xs-12 col-sm-2 col-md-2">
1
</div>
<div className="col-xs-12 col-sm-2 col-md-2 col-half-offset">
2
</div>
<div className="col-xs-12 col-sm-2 col-md-2 col-half-offset">
3
</div>
<div className="col-xs-12 col-sm-2 col-md-2 col-half-offset">
4
</div>
<div className="col-xs-12 col-sm-2 col-md-2 col-half-offset">
5
</div>
<div className="clearfix"></div>
</div>
var cols = $(".container .item").length;
if (cols == 5){
$('div.item').removeClass('col-md-2..etc').addClass('col-md-3').css('width', '20%');
}
Jquery和完成!框架!
如果你不需要完全相同的列宽度,你可以尝试使用嵌套创建5列:
<div class="container">
<div class="row">
<div class="col-xs-5">
<div class="row">
<div class="col-xs-6 column">Column 1</div>
<div class="col-xs-6 column">Column 2</div>
</div>
</div>
<div class="col-xs-7">
<div class="row">
<div class="col-xs-4 column">Column 3</div>
<div class="col-xs-4 column">Column 4</div>
<div class="col-xs-4 column">Column 5</div>
</div>
</div>
</div>
</div>

前两列的宽度为5/12 * 1/2 ~ 20.83%
后三列:7/12 * 1/3 ~ 19.44%
这样的hack在许多情况下给出了可接受的结果,不需要任何CSS更改(我们只使用本机引导类)。
