Important features of Bootstarp: Grid system

For the official explanation, please see the official website: https://v3.bootcss.com/css/#grid

My personal understanding is: within a container container, separated by lines, each line is divided into 12 units of length

//简单的模型
<div class=&#39;container&#39;>
      <div class=&#39;row&#39;> </div>
      <div class=&#39;row&#39;> </div>
      <div class=&#39;row&#39;> </div>
</div>

A simple test:

//c1中没有设置宽度，只设置了div的高度
<div class="container">
    <div class="row">
        <div class="c1 col-lg-1 ">1</div>
        <div class="c1 col-lg-1 ">2</div>
        <div class="c1 col-lg-1 ">3</div>
        <div class="c1 col-lg-1 ">4</div>
        <div class="c1 col-lg-1 ">5</div>
        <div class="c1 col-lg-1 ">6</div>
        <div class="c1 col-lg-1 ">7</div>
        <div class="c1 col-lg-1 ">8</div>
        <div class="c1 col-lg-1 ">9</div>
        <div class="c1 col-lg-1 ">10</div>
        <div class="c1 col-lg-1 ">11</div>
        <div class="c1 col-lg-1 ">12</div>
        <div class="c1 col-lg-1 ">13</div>
    </div>
</div>

 .c1{
            height: 50px;
            background-color: red;
            border: 1px black solid
        }

c1 style

You can see that a container container is divided into 12 parts. This is because col-lg-1 is set. This class can be Set col-lg-1 to col-lg-12,

<div class="container">
    <div class="row">
        <div class="c1 col-lg-3 ">1</div>
        <div class="c1 col-lg-3 ">2</div>
        <div class="c1 col-lg-3 ">3</div>
        <div class="c1 col-lg-3 ">4</div>

    </div>
</div>

The effect is as follows:

There is another important point:

Each column of each row can be further divided

The effect is as follows:

It’s ugly, don’t blame it . .

Code:

<div class="container">
    <div class="row">
       //在这个div里面进行切分
        <div class="c1 col-lg-3  row">
            <div class="c1 col-lg-4 "></div>
            <div class="c1 col-lg-4 "></div>
             <div class="c1 col-lg-4 "></div>
        </div>
       //结束
        <div class="c1 col-lg-3 ">2</div>
        <div class="c1 col-lg-3 ">3</div>
        <div class="c1 col-lg-3 ">4</div>

    </div>
</div>
