Grid System - Stacked-to-horizontal

Let us see a simple grid example with simple layout − two columns, two paragraphs per column. (Here styling for each column is used. You can avoid it.)

<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>
</div>

This will produce the following result −

Details

• <div class = "container">...</div> element is added to ensure proper centering and maximum width for layout.

• Once container is added, next you need to think in terms of rows. Add <div class = "row">...</div> and columns <div class = "col-md-6"></div> inside the rows.

• Every row in the grid is made up of 12 units and you can define the desired size of your columns using those units. In our example we have two columns each made of 6 units wide i.e 6 + 6 = 12.

You can try some more options like − <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>

Experiment and make sure that the sum always needs to be 12.
