Bootstrap Grid System Example: Mobile, Tablet, Desktop

We have already seen medium and large devices. Now, let's look at another example where we will make it suitable for small mobile phones. We will split the columns for tablets into 25%/75%, and we will add the following options:

<div class="col-sm-3 col-md-6 col-lg-4">....</div>
<div class="col-sm-9 col-md-6 col-lg-8">....</div>

This gives us three different column layouts for the three devices. On mobile, it will be a 25% left and 75% right layout. On tablets, it will be a 50%/50% layout. On large viewport devices, it will be a 33%/66% layout. Please check the example below for verification. (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-sm-3 col-md-6 col-lg-8"  
         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-sm-9 col-md-6 col-lg-4" 
         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>

The result is as follows:
