Exciting Features of Bootstrap 4
However, the Twitter Bootstrap is currently the most robust and leading fronted framework that allows developers to develop mobile-first and responsive sites quickly and efficiently.
Although, Bootstrap 4 is still in the development process (avoid using it on a live website). In this blog post, we will explore the new version, known as BootStrap4 that includes a lot of exciting and cool features that will definitely enhance the front-end development workflow.
Let us overview the 10 new and compelling features of Bootstrap 4:
1. Elevated from LESS to SASS
For Bootstrap 4 (new major release), the style rules will be changed from LESS to Sass as its main CSS preprocessor. The Sass is very famous among the frontend developers as it is developer-friendly and also offers more possibilities.
With the help of Libsass Sass Complier, the Bootstrap 4 will be able to compile much quicker than before.
2. Relative CSS Units
Bootstrap 4 drops out the Internet Explorer 8 support. That is a very bold step because it enables them to remove pesky polyfills and transform to relative CSS units. The new Bootstrap release will use REMs and Ems, rather than pixels because it will allow you to execute responsive typography on Bootstrap website. Thus, it will boost the readability, and make a website accessible for the disabled visitors.
3. Brand New Reboot Module
Bootstrap 4 replaces the normalize.css reset file with the brand new Reboot module. It doesn’t eliminate it, but it builds more rules above it. Well, the main objective of this transit was to add all generic CSS selectors and reset styles in the user-friendly and single SCSS file.
In fact, the new reset styles set the box-sizing CSS property into the border-box on the <html> component that is rooted by each child component on the page. The brand new style rule will make responsive layouts more feasible.
4. Enhanced Grid System for Smaller Screen
Bootstrap offers an elegant responsive grid system that enables developers to target devices with different positions. In fact, Bootstrap 3 has 4 grid classes for columns, .col-md-XXfor desktops, .col-lg-XX for bigger desktops, .col-xs-XX for mobile phones and .col-sm-XX for tablets. And now Bootstrap 4 will improve the grid system by adding a fifth grid that will allow developers to target smaller devices (under 480 px width).
In fact, the new grid class has seized the name of the previous smallest one and elevated the current names of the grid tiers by one stage. In Bootstrap 4, the large desktops will utilize the .col-xl-XX class selector. It is also important for you to understand that despite the new name, they did not include a new class for larger screens but for smaller screens.
5. Introduces New Bootstrap Cards
The development team of Bootstrap introduces a new User Interface element, known as Cards to merge its previous elements. The former wells, panels and thumbnails will be replaced by Cards with an objective to provide a sophisticated and seamless workflow to the users. Plus, it will keep relevant components, like titles, headers and footers of thumbnails, panels and wells.
The Cards will become more flexible than the running UI components that allow a bigger space for creative utilizations. In fact, Bootstrap 4 enables you to create your own cards.
6. New Variable Customization Options
All the Sass variables utilized in the Bootstrap4 are added in a single file, known as _variable.scss. that will simplify the development process with ease. You just need to copy the settings from that file into _custom.scss in order to change the default values.
With this, you can customize many elements, including spacing, colors, typography, tables, grid, link styles, column number and gutter width and many more.
7. Enhanced Auto-placement of tooltips and popovers
In Bootstrap 4, tooltips and popovers make a proper use of Tether library, a positioning engine that make it possible to place an absolutely positioned component next to another component on the same page.
8. Opt-in Flexbox Support
You can take an advantage of CSS3’s Flexbox Layout by using Bootstrap 4. However, Internet Explorer 9 doesn’t support the flexbox module because the default version of Bootstrap 4 rather utilizes the float and showcase CSS properties to enable a fluid layout.
Flexbox offers a simple-to-use layout that can be used in responsive design because it provides an adjustable container that either spreads or compresses itself in order to fill the available space in the best possible way.
Note: Use only the opt-in flexbox feature if you don’t need to offer support for Internet Explorer 9.
The bootstrap developers refactored each and every JS plugin for Bootstrap 4 by using Ecma Script6. With the proper use of advanced specifications and the newest enhancements, they aim to boost the frontend experience.
10. Introduce new Utility Class for Spacing
Bootstrap 3 offers various practical utility classes, like the ones that alter floating or the clearfix, but Bootstrap 4 includes more utility classes. With the use of new spacing classes, the developer will instantly change the padding and margins on their websites.
Well, the syntax for the brand new classes is pretty simple, for instance inserting the .m-a-0 class links a style rule that fixes margins to 0 on all sides of the component. On the other hand, margins utilize the m-prefix because paddings are styled only with the p-prefix.
