What is Bootstrap?

It is one of the best front-end frameworks of all times. It has a loyal audience who has been sticking around from the very robust “mobile-first” release of all times, i.e., Bootstrap 3. Also, this overwhelming release holds the responsibility of creating one of the strongest communities ever. And, it’s fairly understandable syntax makes it highly approachable. Not to mention, all it requires is the basic knowledge of HTML and CSS.

Not to mention, the last stable release was back in July 2016 with Bootstrap v3.3.7. And, it’s only preview release been that of version 4.0.0 Beta version in August 2017. Similarly, these data can very well justify the fact that it has been putting in a lot of effort in terms of delivering the best possible results. If observed closely. And, one is definitely going to point out the fact that they have both of their versions available in the market. Although, they suspend work on version 3 in order to intensify their work on the development of version 4.

Still, the question has no answer, which we have come across through many google searches, i.e., “should I use version 4?’ or “should I learn bootstrap 3 or bootstrap 4 in 2017?”

What has really changed in version 4? What it exclusively offers?

The latest Bootstrap 4 beta version releases after 2 years on 10th Aug 2017. Some might call it mostly a rewrite, but it does differ with its predecessors in many possible ways. Some of them are:


In version 4, there is a simple navigation component. Also, it helps to create a new list of elements employing the latest nav base class. Similarly, there are some recent additions like nav-link class, nav-item class and navigation bar styles also.

Appearance & Outlook:

Although, there is not any drastic change in the appearance. Yet, there are certain poignant changes like font implementation size, primary context colour, background colour. Moreover, it is light weight. Hence, it requires manual integration or some other alternative.


Version 3 uses Normalize.css in order to render all the HTML elements their consistent appearance. Similarly, Bootstrap 4 adopted an enhanced version of Normalize.css i.e., Reboot.

Grid system:

Version 4 positions a lot of emphasis on customization. Hence, it’s new grid tier system lets Bootstrap 4 enjoy the presence of up to 5 grid tiers. Thus, one can easily say that it provides access to an improved grid system.


Flexbox is one such layout model that permits the formation of complex layouts with ease. Similarly, it is used to scale elements or apply advanced alignment capabilities, horizontal as well as vertical. Above all, it does not replace the already existing page layout. Additionally, version 4’s major step towards improvement is its movement towards adopting Flexbox.

Form control:

Version 4 offers various improvements in form control. In addition, it enables to deal with the inconsistent input control and its appearance on different browsers. Similarly, it provides custom forms too, in the form of custom checkboxes and radio inputs.


In the version 4, dropdown item class applies to every dropdown item. In fact, the caret symbol is intuitively added to dropdown toggles.


In Bootstrap 3, a pagination component was created by applying the pagination class to any ul element. Now, Bootstrap 4 demands one to properly indicate pagination and link items using page-item as well as page-link class.


As in Bootstrap 3, plugins were divided into two categories, namely, a file including style rules and a Javascript file. Not to mention, there aren’t any poignant changes as to how the plugins are compiled in Bootstrap 4 either. In the latest version, style rules are composed using SASS. Whereas, plugins are available under global jQuery object as Javascript file contains a jQuery section.

Browser support:

Bootstrap 4 offers its immense support to all the major and renowned browsers of all times, like, Safari, Chrome, Opera and Internet Explorer (i8, and above) etc.

Utility classes:

In Bootstrap 4, new utility classes have been included without hampering any existing functionality, whatsoever. Such important additions are as that of responsive text alignment classes, responsive floats, and responsive embedding. Above all, many shortcuts, these, respectively, allow for changing the alignment of the text, floating of the elements and the scaling of the aspect ratio of any embedded media.

Upper hand in using Bootstrap 4 over 3 or Downside?

In the section above, we have talked about the features that Bootstrap 4 exclusively offers. Hence, in order to settle down this raging conflict, we have to pick one. In this Bootstrap 3 vs Bootstrap 4, we need to declare one’s superiority over the other.
