What’s New in the Bootstrap 4 Framework? Bootstrap 4 Tutorial

When it comes to creating amazing, modern websites that display seamlessly on all devices no matter how big or small, the Bootstrap framework has been the norm for several years. The websites that implemented it showed great looks, practical navigation, and delivered this sleek, neat look we’ve grown so used to.

So now, after the great success of version 3, to celebrate the fourth anniversary of the framework and provide more benefits to users and web designers, the development team brings us Bootstrap 4 – which gives the impression of being better, faster, and more flexible than ever. There are several Bootstrap 4 Templates available that will help you build an amazing website with ease.

That is very good news, but as you probably already know, the framework itself is made up of a couple of CSS and Javascript files, which alone do not help the general public in the least to create much-desired web content.

Most of us, including myself, do not create websites by writing the code and updating the browser to see the results – we generally use the most convenient and quick way – with the help of web page creation software, and we regularly have to wait until that the latest development advances are included in the product we rely on. Will this scenario repeat itself once again?

I discovered Mobirise’s Bootstrap-based Website Builder not too long ago and almost instantly became addicted to this software’s approach to creating fully responsive and highly aesthetic-looking websites made in Bootstrap 3.

The way it is As things unfolded it seemed so natural and close to the graphic design process I was used to, that I stopped googling other website builders – I decided that when it came to web design, this would be my tool.

Bearing in mind what has already been saying about the limitations of software in general when it comes to staying up-to-date with the latest in development, I received the news of the Bootstrap 4 release with mixed feelings.

So imagine my surprise when I did some deep research on my favorite website building software and found that the latest, and probably the best, web design framework was already waiting for me on my desktop after my last update too! Mobirise!

All you need is a powerful story to tell the world and some basic skills. Since we talked about how those who are complete beginners can build extraordinarily good websites from scratch, in this article we will take a closer look at the improvements in appearance and functionality that come from designing with Mobirise’s Bootstrap-based Website Builder and with Bootstrap 4 fully incorporated into the PurityM Bootstrap theme.

It doesn’t matter if you are a general user, a graphic designer who needs to create a website,

So what’s new in Bootstrap 4 – Bootstrap 4 Tutorial

Goodbye pixels, hello rem

Exploring the CSS for the new PurityM Bootstrap theme project, I opened it up to see what all the fuss was about, maybe the first thing I noticed was the dimensions. The old absolute pixel dimensions were no longer there – rem relative units took their place to become the default in Bootstrap 4.

While pixels have a fixed value of 1/96 of an inch, rem units are relative to another property length – the font size of the root element.

The More Flexible Grid system

Another grid-level – xl adds to xs, sm, md, and lg. It handles the grid system in viewpoints wider at 75em or in the case of Bootstrap’s default global font size 4 – 1200 px.

Inverse Tables

Bootstrap 4 introduces new classes for inverting table colors. The new class is table-inverse – it goes directly after the table class in declarations. It is also possible to just invert the header section using the thread-inverse class.

Another new feature that Bootstrap-4 introduces is reflow tables – rows and columns are reversed, and depending on the width of the viewport, some of the content may “reflow” to the next row.


In Bootstrap 4 there are seven different types of semantic buttons: Primary, Info, Success, Warning, Danger, Link, and the new secondary button class. Bootstrap 3’s default button is being removed. Another new feature is the predefined appearance of the outline of these classes that is obtained by adding “-outline” to the corresponding class.

For example: “btn-primary-outline”. All of the Bootstrap 4 button classes can be freely used in Mobirise’s Bootstrap Builder – it even has two bonus classes – black and white, as a clear monochrome appearance is sometimes needed for an overall view. To make it easier to build your site, you will have instant access to all the major classes and the Secondary outline as they are the most commonly used.

As far as sizes go in Bootstrap 4, the little-used .btn-xs class is being removed. In addition to the default button size, you can use the small “btn-sm” and large “btn-lg” options. Since we are building websites with responsive, readable, and easy-to-use screen widths on any device, the default button size in the Mobirise Builder is Large.
