引导程序中有7个相等的列

Question

我想知道是否有人可以解释我如何在引导程序中获得7个相等的列？我正在尝试制作日历.这段代码似乎做了5:

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>

我的主要内容有以下几个类,所以我希望7列可以放在这个内容中:

COL-LG-12

任何人都可以解释这是否可能,或者我是否必须坚持偶数？

Answer 1

好吧,IMO你可能需要width使用CSS3 @media查询来覆盖列.

这是我尝试创建7-col网格系统:

<div class="container">
  <div class="row seven-cols">
    <div class="col-md-1">Col 1</div>
    <div class="col-md-1">Col 2</div>
    <div class="col-md-1">Col 3</div>
    <div class="col-md-1">Col 4</div>
    <div class="col-md-1">Col 5</div>
    <div class="col-md-1">Col 6</div>
    <div class="col-md-1">Col 7</div>
  </div>
</div>

@media (min-width: 768px){
  .seven-cols .col-md-1,
  .seven-cols .col-sm-1,
  .seven-cols .col-lg-1  {
    width: 100%;
    *width: 100%;
  }
}

@media (min-width: 992px) {
  .seven-cols .col-md-1,
  .seven-cols .col-sm-1,
  .seven-cols .col-lg-1 {
    width: 14.285714285714285714285714285714%;
    *width: 14.285714285714285714285714285714%;
  }
}

/**
 *  The following is not really needed in this case
 *  Only to demonstrate the usage of @media for large screens
 */    
@media (min-width: 1200px) {
  .seven-cols .col-md-1,
  .seven-cols .col-sm-1,
  .seven-cols .col-lg-1 {
    width: 14.285714285714285714285714285714%;
    *width: 14.285714285714285714285714285714%;
  }
}

价值width来自:

width = 100% / 7 column-number = 14.285714285714285714285714285714%

其他选择

此外,您可以使用自定义生成器(更改@grid-columns,...)构建自己的7列版本的Twitter Bootstrap .

如果您使用较少的编译器,您可以下载较小版本的Twitter Bootstrap(来自Github)并编辑该variables.less文件.

Answer 2

一个几乎相等,快速的解决方案.没有自定义CSS.

.cell {
  border: 1px solid black;
  text-align: center;
  flex-basis: 33.3333%;
  flex-grow: 0;
  flex-shrink: 0;
  -webkit-box-flex: 0;
  -webkit-tap-highlight-color: #0000;
}

Answer 3

升级到Bootstrap 4可能是一个不错的选择.

附带等宽列的类col

<div class="row">
  <div class="col"></div>
  <div class="col"></div>
  <div class="col"></div>
  <div class="col"></div>
  <div class="col"></div>
  <div class="col"></div>
  <div class="col"></div>
</div>

https://v4-alpha.getbootstrap.com/layout/grid/#equal-width

提示:如果要在屏幕低于md时在新行中打破列,请在每列之后添加此div:

<div class='w-100 d-md-none'></div>

.w-100打破一个新行,而.d-md-done隐藏了比md宽的屏幕上的div

所以它会给:

<div class="row">
  <div class="col"></div>
  <div class='w-100 d-md-none'></div>
  <div class="col"></div>
  <div class='w-100 d-md-none'></div>
  <div class="col"></div>
  <div class='w-100 d-md-none'></div>
  <div class="col"></div>
  <div class='w-100 d-md-none'></div>
  <div class="col"></div>
  <div class='w-100 d-md-none'></div>
  <div class="col"></div>
  <div class='w-100 d-md-none'></div>
  <div class="col"></div>
</div>

Answer 4

我想要一个更精确的解决方案,所以我创建了一个特殊的row/col类集(语义上与日历的概念相关).

这破坏了Bootstrap构建基础网格(in grid-framework.less)的方式.它保留了xs,sm,md,和lg类在不同的视口定制网格.

注意:这只包括网格样式; 你仍然需要写下其余的东西,使它看起来像一个日历.

标记

<div class="row">
    <div class="col-xs-7">
        <div class="calendar">
            <div class="calendar-row">
                <div class="calendar-xs-1">Sunday</div>
                <div class="calendar-xs-1">Monday</div>
                <div class="calendar-xs-1">Tuesday</div>

        </div>
    </div>
    <div class="col-xs-5">
        This container intentionally left blank.
    </div>
</div>

该 .less

/*

@calendar-columns:      7;
@calendar-gutter-width: 0px;

.make-calendar-columns() {
  // Common styles for all sizes of calendar columns, widths 1-12

Answer 5

按照安东尼·吉布斯的回答，您可以简单地使用Boostrap 4“ col ” css类：

<div class="row">
  <div class="col">Mon</div>
  <div class="col">Tue</div>
  <div class="col">Wen</div>
  <div class="col">Thu</div>
  <div class="col">Fri</div>
  <div class="col">Sat</div>
  <div class="col">Sun</div>
</div>

你不一定需要引导4，你总是可以简单地从BS4的CSS声明复制到自己的样式表。

/* Equal width */
.col {
  -ms-flex-preferred-size: 0;
  flex-basis: 0;
  -webkit-box-flex: 1;
  -ms-flex-positive: 1;
  flex-grow: 1;
  max-width: 100%;
}

/* Add gutters */
.col {
  position: relative;
  width: 100%;
  min-height: 1px;
  padding-right: 15px;
  padding-left: 15px;
}

这具有BS4准备的好处，一旦你迁移，它也给使用5，7，9或11列的可能性。

Answer 6

您的问题是列数奇数，因此无法实现对称。因为每一列都是一周中的某一天，所以您可以说所有工作日都有col-md-2课程，而其他两天都有col-md-1课程。

该方法将基于周六和周日需要较少空间的假设而起作用，但是我不知道这是否适合您的情况。

<div class="row">
    <div class="col-md-2">Mon</div>
    <div class="col-md-2">Tue</div>
    <div class="col-md-2">Wen</div>
    <div class="col-md-2">Thu</div>
    <div class="col-md-2">Fri</div>
    <div class="col-md-1">Sat</div>
    <div class="col-md-1">Sun</div>
</div>
<div class="row">
    <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">6</div>
    <div class="col-md-1">7</div>
</div>
