There are actually several components driving Bootstrap’s popularity- namely, it is open-source and thus free to download and use, it’s completely customizable, and it is compatible with all modern browsers.
What sets Bootstrap apart from other development toolkits is the fact that it was created mobile-first. Which means, the code was optimized for mobile devices (i.e. the smallest screen size) very first after which scaled as much as display on larger screens. As a result, developing with Bootstrap CSS ensures that your site supports proper rendering and touch zooming for all devices.

Now that we fully grasp what Bootstrap CSS is and who really should be using it, let’s briefly discuss the different download options you've got.
How you can Download Bootstrap CSS
Prior to we stroll via the process of downloading Bootstrap, it is important to note that you can load Bootstrap remotely by means of BootstrapCDN instead of downloading it. Due to the fact this will likely need guests to possess an internet connection to visit your site and can require you to post far more code, even so, downloading Bootstrap is the much more popular selection.
There are two distinct kinds of Bootstrap obtainable for download. Each and every version - a precompiled in addition to a source code version - appeal to various customers based on no matter whether they prioritize ease-of-use or flexibility. Let’s take a closer look at each below.
Precompiled Bootstrap
The precompiled version is the most simple kind of Bootstrap. You will download precompiled CSS and JS files and minified CSS and JS files that happen to be uncomplicated to drop in almost any web project.
After downloaded, you’ll unzip the compressed folder and see the following structure.
bootstrap/
-- css/
¦ -- bootstrap-grid.css
¦ -- bootstrap-grid.css.map
¦ -- bootstrap-grid.min.css
¦ -- bootstrap-grid.min.css.map
¦ -- bootstrap-reboot.css
¦ -- bootstrap-reboot.css.map
¦ -- bootstrap-reboot.min.css
¦ -- bootstrap-reboot.min.css.map
¦ -- bootstrap.css
¦ -- bootstrap.css.map
¦ -- bootstrap.min.css
¦ -- bootstrap.min.css.map
-- js/
-- bootstrap.bundle.js
-- bootstrap.bundle.js.map
-- bootstrap.bundle.min.js
-- bootstrap.bundle.min.js.map
-- bootstrap.js
-- bootstrap.js.map
-- bootstrap.min.js
-- bootstrap.min.js.map
Using the compiled version is less complicated and more rapidly to work with than the supply code version - but it’s extra hard to customize. Any transform you want to create to a pre-styled element or layout must be applied with an override towards the existing types.
If you need to customize the CSS and JS files incorporated in Bootstrap as you please, then you’ll be better off downloading the source code version.
Bootstrap Source Code
The source code version involves the precompiled CSS, JS, and font assets as well as source files for the CSS, JS, and icon fonts respectively. If you pick to download the Bootstrap source code, then you will unzip the folder and see the following structure.
bootstrap/
-- dist/
¦ -- css/
¦ -- js/
-- site/
¦ --docs/
¦ -- 4.4/
¦ -- examples/
-- js/
-- scss/
The dist/ folder consists of every little thing listed inside the precompiled section above. The docs/ folder incorporates the supply code for Bootstrap documentation and examples of Bootstrap usage. The js/ folder consists of the source code for Bootstrap JS plus the scss/ folder for Bootstrap CSS.
Because this version of Bootstrap calls for you to have Autoprefixer as well as a SASS compiler, the set-up process is longer and more tricky than setting up the pre-compiled version. When set up, on the other hand, you may adjust and customize the files any way you'd like.
Each version of Bootstrap is best for distinct use cases, but because the precompiled Bootstrap is simpler and more quickly to make use of, we’ll concentrate on that version for the rest in the post. Below let’s look at how you'll be able to make use of the precompiled Bootstrap to develop a website.
