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?

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

我看了所有的答案，没有找到“显而易见的答案”。基本上，您需要做的是选取任何自举列(例如col-2)并编辑一些值。在这个例子中，我使用的是.col-custom类。
5个相等的列表示每个列占用20%，因此:flex:0 0 20%和max-width:20%。同样的方法，你可以创建其他数量的列(7,9,11,84或任何你想要的)。
您可以创建自定义宽度的CSS变量，并在项目中使用它。就像这样:
:root {
--col-custom: 20%;
}
.col-custom {
flex: 0 0 var(--col-custom);
max-width: var(--col-custom);
}
工作的例子:
.col-custom, .col-sm-custom, .col-md-custom, .col-lg-custom, .col-xl-custom { position: relative; width: 100%; padding-right: 15px; padding-left: 15px; } .col-custom { flex: 0 0 20%; max-width: 20%; } @media (min-width: 576px){ .col-sm-custom { flex: 0 0 20%; max-width: 20%; } } @media (min-width: 768px){ .col-md-custom { flex: 0 0 20%; max-width: 20%; } } @media (min-width: 992px){ .col-lg-custom { flex: 0 0 20%; max-width: 20%; } } @media (min-width: 1200px){ .col-xl-custom { flex: 0 0 20%; max-width: 20%; } } /*DEMO*/ .col-custom,.col-sm-custom,.col-md-custom,.col-lg-custom,.col-xl-custom{height:100px;border:1px red solid} <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css"> <div class="container-fluid"> <div class="row"> <div class="col-sm-custom"></div> <div class="col-sm-custom"></div> <div class="col-sm-custom"></div> <div class="col-sm-custom"></div> <div class="col-sm-custom"></div> </div> </div>
我对这个问题的首选方法是基于make-grid-columns mixin，利用现有的Bootstrap变量创建一个SASS mixin。
// Custom Grid Columns
//
// $name - determines the class names: eg. ".col-5ths, .col-sm-5ths ..."
// $size - determines the width (2.4 is one fifth of 12, the default number of columns)
@mixin custom-grid-columns($name, $size, $grid-columns: $grid-columns, $breakpoints: $grid-breakpoints) {
$columns: round($grid-columns / $size);
%custom-grid-column {
@include make-col-ready();
}
@each $breakpoint in map-keys($breakpoints) {
$infix: breakpoint-infix($breakpoint, $breakpoints);
.col#{$infix}-#{$name} {
@extend %custom-grid-column;
}
@include media-breakpoint-up($breakpoint, $breakpoints) {
// Create column
.col#{$infix}-#{$name} {
@include make-col($size);
}
// Create offset
@if not ($infix=="") {
.offset#{$infix}-#{$name} {
@include make-col-offset($size);
}
}
}
}
}
然后可以调用mixin来生成自定义列类和偏移量类。
@include custom-grid-columns('5ths', 2.4);
Bootstrap默认可以缩放到12列?这意味着如果我们想要创建一个宽度相同的12列布局，我们将在div class="col-md-1"中写入12次。
<div class="row">
<div class="col-md-1"></div>
<div class="col-md-2">1</div>
<div class="col-md-2">2</div>
<div class="col-md-2">3</div>
<div class="col-md-2">4</div>
<div class="col-md-2">5</div>
<div class="col-md-1"></div>
</div>
5列布局与Twitter引导风格
.col-xs-15 {
position: relative;
min-height: 1px;
padding-right: 10px;
padding-left: 10px;
}
.col-xs-15 {
width: 100%;
float: left;
}
@media (min-width: 768px) {
.col-xs-15 {
width: 50%;
float: left;
}
}
@media (min-width: 992px) {
.col-xs-15 {
width: 20%;
float: left;
}
}
@media (min-width: 1200px) {
.col-xs-15 {
width: 20%;
float: left;
}
}
