Bootstrap is known as a mobile-first web layout and Bootstrap is a powerful front-end framework for the faster development of responsive websites.
There’s a debate every time over which is better for web designers or developers, Sass or LESS? Those used Sass will be pleased to hear that Bootstrap is now officially using Sass with there project. When you will download the Bootstrap source you’ll find a folder called “Sass” in which you’ll see all the necessary partials. “_variables.scss” contains all the variables and settings you’ll need, then “bootstrap.scss” houses all the @import directives, allowing you to customize your Bootstrap installation by including or excluding whichever components you wish.
Lets talk about the new exiting feature that come with Bootstrap 4
#1. New Grid System
The Bootstrap Grid is used for layout, specifically Responsive Layouts. The Grid is work with of groupings of Rows & Columns inside 1 or more
Bootstrap 3 currently has 4 grid classes for columns, .col-xs-* for mobile phones, .col-sm-*(768px & up) for tablets, .col-md-*(992px & up) for desktops, and .col-lg-*(1200px & up) for larger desktops.
In Bootstrap 4, these media queries, prefixes and breakpoints has been changed. Here’s the list with their media queries:
- col- : (extra small, less than 576px)
- col-sm- : (small, 575px and up)
- col-md- : (medium, 768px and up)
- col-lg- : (large, 992px and up)
- col-xl- : (extra large, 1140px and up)
Bootstrap 4 has another breakpoint, “extra large”.
Example of 3 grid with container
<div class="container"> <div class="row"> <div class="col-sm"> One of three columns </div> <div class="col-sm"> One of three columns </div> <div class="col-sm"> One of three columns </div> </div> </div>
The other thing to note is that we no longer write a prefix for “extra small”. We simply write ‘col-*’ and it’s implied that it’s extra small.
In Bootstrap 3, the layout and grid system was based on the float property of CSS. This worked well for most people. Bootstrap 4 is now based on Flexbox. If your layout based on the layout and grid system on Flexbox allows for some great options when creating your layouts.
Bootstrap 4 flexbox simply allows you to take full advantage of the flexbox-based grid system and the components.
