Bootstrap Grid System Example: Medium and Large Devices

In the Example: Stacked to Horizontal, we have already looked at the basic grid system. Here, we use 2 divs and split them 50%/50% at the middle of the viewport width:

<div class="col-md-6">....</div>
<div class="col-md-6">....</div>

However, on large devices, you eventually design them to be 33%/66%. So what we need to do is to be ready to change the column widths at the breakpoint:

<div class="col-md-6 col-lg-4">....</div>
<div class="col-md-6 col-lg-8">....</div>

Now Bootstrap will look for classes with md in medium devices and use them. On large devices, it will look for classes with lg and use them. In this example, our 2 divs will change from a 50%/50% split to a 33%/66% split. Please check the example below to verify. (Here, styles are defined for each column separately, which you can avoid.)

Example

<div class="container">
   <h1>Hello, world!</h1>

   <div class="row">

      &lt;div class="col-md-6 col-lg-4"  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>

      &lt;div class="col-md-6 col-lg-8" 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>
