In this article, I will explain Container Class in Bootstrap. Basically, we use containers to create the layout of a web page. In Bootstrap, containers are the most fundamental elements for creating layout. While, the containers enclose rows of elements. Further, rows may contain columns.

We have different container classes in Bootstrap 4. The following list describes these classes.

.container. Basically, it is the responsive container. So, at each break point it sets the max-width of that break point. For instance, if the break-point is 540px, it sets the max-width to 540px. Further, it is the fixed-width container.
.container-fluid. Whenever we need a full width ccontainer, we use this type of container. In other words, for each breakpoint, width is always 100%.

Apart from above containers, Bootstrap 4 has other containers. These containers are specific to a breakpoint. For instance, in case of .container-sm, width remains 100% for extra small screens which are less than 576px. Further, for small screens (more than 576 px), width is 540 px. Similarly, for medium screens, the width is 720px, for large screen, it is 960px, and for extra large, the width is 1140px.

Likewise, .container-xl sets the width to 1140px for extra large screens. However, for all smaller screens, the width remains 100%. Similarly, we can also use .container-md and .container-lg. All these containers set width to 100% till the specific breakpoint is reached.

The following example demonstrates the use of container class.

    <style>
	.mydiv{
	   height: 500px;
           padding: 10px;
	}
    </style>
 </head>
 <body>
   <div class="container mydiv" style="background: #aadd99">
       <h1 class="text-center">Bootstrap Container Example</h1>
   </div>
 </body>
</html>
