Bootstrap grid system Example: stack level

Let's look at a simple instance with a grid layout: two columns, each column contains two paragraphs. (Here, the columns are defined for each style, you can avoid doing so.) 

<! DOCTYPE html>
<Html>
<Head>
   <Title> Bootstrap instance - stacked horizontal </ title>
   <Link href = "/ bootstrap / css / bootstrap.min.css" rel = "stylesheet">
   <Script src = "/ scripts / jquery.min.js"> </ script>
   <Script src = "/ bootstrap / js / bootstrap.min.js"> </ script>
</ Head>
<Body>

<Div class = "container">
   <H1> Hello, world! </ H1>

   <Div class = "row">

      <Div class = "col-md-6" style = "background-color: # dedef8; box-shadow: 
         inset 1px -1px 1px # 444, inset -1px 1px 1px # 444; ">
         <P> Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do 
            eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut 
            enim ad minim veniam, quis nostrud exercitation ullamco laboris 
            nisi ut aliquip ex ea commodo consequat. 
         </ P>

         <P> Sed ut perspiciatis unde omnis iste natus error sit voluptatem 
            accusantium doloremque laudantium, totam rem aperiam, eaque ipsa 
            quae ab illo inventore veritatis et quasi architecto beatae vitae 
            dicta sunt explicabo. 
         </ P>
      </ Div>

      <Div class = "col-md-6" style = "background-color: # dedef8; box-shadow: 
         inset 1px -1px 1px # 444, inset -1px 1px 1px # 444; ">
         <P> Sed ut perspiciatis unde omnis iste natus error sit voluptatem 
            accusantium doloremque laudantium.
         </ P>

         <P> Neque porro quisquam est, qui dolorem ipsum quia dolor sit amet, 
            consectetur, adipisci velit, sed quia non numquam eius modi 
            tempora incidunt ut labore et dolore magnam aliquam quaerat 
            voluptatem. 
         </ P>
   </ Div>
</ Div>

</ Body>
</ Html>

The results are as follows:

Stacked horizontal grid system
detail
  • <div class = "container"> ... </ div> element has been added to ensure that the maximum width and center.
  • Once you add the container, then you need to consider the behavior of the unit. Add<div class = "row"> ... </ div>, and add columns within the line <div class = "col-md-6"> </ div>.
  • Each row in the grid is made up of 12 units, you can use these elements to define the size of the columns. In our example, there are two columns, each column consists of six units, or 6 + 6 = 12.

You can try many more options, such as<div class = "col-md -3"> </ div> and <div class = "col-md-9"> </ div> or<div class = "col -md-7 "> </ div> and<div class =" col-md-5 "> </ div>.

You can try, but make sure that the sum is always 12.
