What is Bootstrap and How Do I Use It?

 /  220 responses

If you have any sort of interest in web development, you’ve likely heard of Bootstrap. According to the official website, Bootstrap is the most popular HTML, CSS, and JS framework for developing responsive, mobile first projects on the web. Sounds great! Now how do I use it?

It would be easy to send you over to their Getting Started page and call it a day. Their setup guide is indeed a host of useful information – links to CDNs, explanations on how to install with Bower, npm, and Composer, information on integration with Autoprefixer and LESS, a bunch of templates, licenses, and translations – but it is certainly not a step by step guide to getting started (which very well might be in the spirit of autodidactism).

When I discovered Bootstrap a few years ago, responsive design was still gaining in popularity, and not necessarily the expected norm. Having only ever made websites from scratch, I was a little confused about the entire concept of a framework. I’d imagine it’s even more confusing for beginners who are now expected to learn responsive design concepts and Bootstrap and JavaScript libraries, in addition to HTML, CSS and JS.

This guide is meant as a first look into Bootstrap for beginners, so won’t be going into LESS and Sass integration, which are more intermediate/advanced concepts. While it’s written for the current, stable version Bootstrap 3, the concepts will remain the same for future versions.


  • Learn what a front-end framework is and how it can be useful
  • Understand how to properly include Bootstrap’s CSS and JavaScript and begin customizing


  • Basic knowledge and understanding of HTML and CSS

What is Bootstrap?

Bootstrap can be boiled down to three main files:

Additionally, Bootstrap requires jQuery to function. jQuery is an extremely popular and widely used JavaScript library, that both simplifies and adds cross browser compatibility to JavaScript.

Everything else you might happen across while studying the Bootstrap documentation – Grunt, Gulp, Sass, LESS, bower, npm, etc – is not necessary to get started with Bootstrap. These are task runners, preprocessors, installation aids, and package managers, so don’t be discouraged if you don’t know how to use any of them yet.

Why is a framework important? Do I need to use one?

You absolutely don’t need to use a framework – I recently wrote an article called You Don’t Need a Framework: Understanding the Fundamentals of Responsive Design, which I would recommend reading if you want to learn more about responsive design. However, frameworks are very popular and have many benefits, so it’s important to learn how to work with them.

Some of the ways that frameworks can help you:

  • Prevent repetition between projects
  • Utilize responsive design to allow your website to adapt to various screen sizes – mobile, desktop, and everything in between
  • Add consistency to design and code between projects and between developers
  • Quickly and easily prototype new designs
  • Ensure cross-browser compatibility

Generally, every web project you work on will need to be responsive and work properly on all the major browsers, and likely have some fallbacks for older browsers. Bootstrap has a huge open source community that works on covering this so you don’t have to. Additionally, when multiple developers all know the same system, they can work in better harmony – and it also makes it easier for newcomers on a project to get up to speed.

The grid is probably one of the most essential aspects of the framework. It’s the basis on which the entire layout is created. Beyond that, Bootstrap’s core CSS will also add helpful styling to forms, tables, buttons, lists, and images, as well as fully functioning navigation bars, while the core JavaScript will add helpful code for creating modals, carousels, alerts, popups, dropdowns, and accordions.

Let’s begin!

Building a Basic Template with Bootstrap

Bootstrap comes with a few very simple examples to start from, but it’s just as easy to start from “scratch”, so that’s what we’ll do. First, I’ll use only Bootstrap to lay out the foundation, then we’ll add our own custom style on top to make something fun and trendy.

Step one is to download Bootstrap. The zip file will come with css, fonts, and js directories. Unzip that and save the files in some directory. Bootstrap doesn’t come with any HTML, but they have a “Hello, World!” page to start on the documentation, so we’ll use that as index.html.

Hello, World!

<!DOCTYPE html>
<html lang="en">
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <title>Bootstrap 101 Template</title>
    <link href="css/bootstrap.min.css" rel="stylesheet">
    <!--[if lt IE 9]>
      <script src="https://oss.maxcdn.com/html5shiv/3.7.2/html5shiv.min.js"></script>
      <script src="https://oss.maxcdn.com/respond/1.4.2/respond.min.js"></script>
    <h1>Hello, world!</h1>

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
    <script src="js/bootstrap.min.js"></script>

Easy enough to start. We have our basic doctype, html, head and body tags. The meta name="viewport" tag is particularly important for responsive design – it ensures that your website has a 1:1 ratio with the viewport (screen size).

Beyond that, we’re just adding Bootstrap core CSS in the <head>

<link href="css/bootstrap.min.css" rel="stylesheet">

jQuery via Google CDN before the closing </body> tag…

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>

and Bootstrap core JavaScript.

<script src="js/bootstrap.min.js"></script>

Bootstrap JavaScript and custom JavaScript must go below jQuery to function! Additionally, we can link to jQuery via Google’s URL because it reduces load on our live server, but you can download it if you want to work locally.

Well, that’s all you need to get started with Bootstrap! Let’s check out our awesome new site.


Navigation Bar

Although we have nothing, in no time at all we can get copying and pasting from the docs and have a nice, functioning website. First and foremost, we add in the quintessential Bootstrap top navigation bar. I made a simplified version of their navbar example. Place this code right below your opening <body> tag.

<nav class="navbar navbar-inverse navbar-static-top">
	<div class="container">
		<div class="navbar-header">
			<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
				<span class="sr-only">Toggle navigation</span>
				<span class="icon-bar"></span>
				<span class="icon-bar"></span>
				<span class="icon-bar"></span>
			<a class="navbar-brand" href="#">Balance Web Development</a>
		<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
			<ul class="nav navbar-nav navbar-right">
				<li><a href="#">About</a></li>
				<li class="dropdown">
					<a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Services<span class="caret"></span></a>
					<ul class="dropdown-menu">
						<li><a href="#">Design</a></li>
						<li><a href="#">Development</a></li>
						<li><a href="#">Consulting</a></li>
				<li><a href="#">Contact</a></li>

It seems like a confusing mess, but it’s not so complicated. In the first line, I’m defining the entire bar as a navbar, choosing a dark color scheme with navbar-inverse, and electing to use navbar-static-top, as opposed to a fixed (sticky) header.

<nav class="navbar navbar-inverse navbar-static-top">

A container sets a max-width on the content within your full-width navbar.

<div class="container">

The navbar-header class contains the “brand” information, where you can put your logo or company name. We’re making a website for fictional tech company Balance Web Development (well, it’s better than their old site!).

The button is hidden on desktop, and becomes a dropdown hamburger menu on mobile (each <span class="icon-bar"> is a line in the hamburger).

<div class="navbar-header">
	<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
		<span class="sr-only">Toggle navigation</span>
		<span class="icon-bar"></span>
		<span class="icon-bar"></span>
		<span class="icon-bar"></span>
	<a class="navbar-brand" href="#">Balance Web Development</a>

The rest of the code is a right-aligned unordered list that servers as both our desktop and mobile menu.

Jumbotron Header

I decided I want one of those big, space-wasting, attention-grabbing headers, which is called a jumbotron in Bootstrap terms. Not much to see here, just a jumbotron with a container and some copy.

<div class="jumbotron">
	<div class="container">
		<h1>Ready. Set. Code.</h1>
		<p>Are you ready to boilerstrap your cross-compatible buzzword? We're Sassy, flat and semantic, so what are you waiting for?</p>
		<p><a class="btn btn-primary btn-lg" href="#" role="button">Download Free Trial »</a> <a class="btn btn-primary btn-lg" href="#" role="button">Learn more »</a></p>

There’s some extra space we don’t want, but I want to see how far Bootstrap can get us without overriding styles. As you can see, we already have a pretty nice, adaptable layout without having written a single line of CSS.


The last thing I’ll do is add in some main content, which will be be in the form of a grid. Grids are rows…

<div class="row">

that contain columns.

<div class="row">
  <div class="col-md-6"></div>
  <div class="col-md-6"></div>

Bootstrap works on a 12-column system, so as long as you add up to 12, you’re golden. The above example will contain two 50% width columns (6/12), which will stack on mobile and become 100% width.

<div class="container">
	<div class="row">
		<div class="col-md-4">
			<span class="glyphicon glyphicon-cloud" aria-hidden="true"></span>
			<h3>Cloud Computable</h3>
			<p>Donec id elit non mi porta gravida at eget metus. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh.</p>
		<div class="col-md-4">
			<span class="glyphicon glyphicon-floppy-disk" aria-hidden="true"></span>
			<h3>Backwards Compatible</h3>
			<p>Etiam porta sem malesuada magna mollis euismod. Donec sed odio dui. Lorem ipsum dolor.</p>
		<div class="col-md-4">
			<span class="glyphicon glyphicon-console" aria-hidden="true"></span>
			<h3>GUI Free</h3>
			<p>Vestibulum id ligula porta felis euismod semper. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh.</p>

Here you can see I have three four-of-twelve columns, and as 3 x 4 = 12, everything works out.


I’ve also added in a few glyphicons for decoration. Glyphicons is the built-in icon set that comes with Bootstrap. If you don’t load your fonts, or if you move them to a different directory, these icons won’t work.

<span class="glyphicon glyphicon-floppy-disk" aria-hidden="true"></span>

Using a glyphicon will always be that same code, and only the glyphicon-floppy-disk class will change.

I am now satisfied with the foundation of my layout.

Adding Custom Styles to Bootstrap

Not bad for getting this far without touching a line of style. It’s professional, responsive, and browser friendly. It’s definitely not creative or unique, though. After laying down a foundation, you’ll want to add your own personal design.

If you know LESS or Sass, you can play around in Bootstrap’s extensive customization area and download your own version of Bootstrap. We happen to be using “vanilla CSS”, which is CSS without a preprocessor. Fortunately, you can just add an additional stylesheet below Bootstrap’s core

Don’t modify the Bootstrap core – you’re much better off overriding the existing styles.

<link href="css/bootstrap.min.css" rel="stylesheet">
<link href="css/custom.css" rel="stylesheet">
<link href='https://fonts.googleapis.com/css?family=Montserrat:400,700' rel='stylesheet' type='text/css'>

I added a link to a Google font called Montserrat. If you’ve never used a Google Font before, all you have to do is add the font stylesheet to your head and change the font-family of your desired element.

Now we finally begin styling. In just a few minutes, I’ll be able to transform my boring, generic Bootstrap layout into a fun, flat layout. First, I’m going to get rid of that pesky space between the navbar and the jumbotron.

.navbar {
	margin-bottom: 0;

A few simple styles to the main tags. I’m loading in the Montserrat font on the entire page, I’ve made the headers bold, and I’ve made the background dark and the text light.

body {
	background: #3E4649;
	color: #f7f7f7;
	font-family: 'Montserrat', sans-serif;
h2 {
	font-weight: bold;
p {
	font-size: 16px;
	color: #cdcdcd;

I’m going to make the jumbotron green and centered.

.jumbotron {
	background: #27A967;
	color: white;
	text-align: center;
.jumbotron p {
	color: white;
	font-size: 26px;

I’m going to turn the buttons into “ghost buttons”, which are buttons that are transparent with a border. I’m also adding a margin so they’ll stack properly on mobile.

.btn-primary {
	color: #fff;
	background-color: transparent;
	border-color: white;
	margin-bottom: 5px;
.btn-primary:hover {
	color: #27A967;
	background-color: white;
	border-color: white;

I’m going to make the navbar a different shade of dark, make the links lighter, and change the background color on hover.

.navbar-inverse {
	background: #2E2F31;
	border: 0;
.navbar-inverse .navbar-nav li a {
	color: #f7f7f7;
	font-size: 16px;
.navbar-inverse .navbar-nav li a:hover {
	background: #27A967;

The dropdown menu has its own classes, so I’m also going to change the background color on these and add a little padding.

.dropdown-menu {
	background: #2E2F31;
	border-radius: 0;
	border: 0;
.dropdown-menu li a {
	padding: 10px;
.navbar-inverse .navbar-nav .dropdown-menu li a:hover {
	background: #2C463C;

Back in my HTML, I’m going to wrap a section tag around my grid, and call it call-to-action. I’m also going to create a glyphicon-large class and add it to each icon span.

<section class="call-to-action">
<!-- .rows and .columns -->
  <span class="glyphicon glyphicon-cloud glyphicon-large" aria-hidden="true"></span>
<!-- /.rows and .columns -->

The final touches to my code are going to be centering the bottom call-out, adding margin-bottom to the p tags so they stack properly on mobile, and making my glyphicons bigger.

.call-to-action {
	text-align: center;
.call-to-action p {
	margin-bottom: 30px;
	font-family: sans-serif;
.glyphicon-large {
	font-size: 100px;

With one small page worth of code, I’ve completely transformed my layout. From here, you can be much more creative.

Of course, I also put the demo up as a Codepen.

See the Pen Start Bootstrap by Tania (@taniarascia) on CodePen.


Hopefully you learned a bit about Bootstrap and frameworks from this tutorial. This is hardly scratching the surface of what Bootstrap is capable of – but you can take it from here. The documentation is enormous, and if ever you can’t figure out how to do something, chances are a quick Google search will point you in the right direction.

I would encourage you to play around and make your own framework for personal projects to aid in your understanding of responsive design.

    Best bootstrap tutorials for beginners. I was banging my head to figure this out but your tutorial helped me.

    How can I get the text inside ‘navbar-brand’ to be at center of the glyph icon. Currently in this tutorial icon and text are on same line, I want text to shit up so it is in the middle of the icon.

    I tried span wrap the text and adjust line height, margin and padding. But nothing seems to work.

    Hey Tania, I’ve just started learning web development. I know the basics of HTML, CSS and a bit of JavaScript. Is that knowledge enough to understand Bootstrap?
    And also are there any other things I need to know to get a career in Web Development?

    Please help me with my queries.Thanks.

    (PS: That’s a great article there. Was a very interesting read)

    • Tania says:


      Is that knowledge enough to understand Bootstrap?

      Sure, basic HTML, CSS and JavaScript is more than enough to start using Bootstrap.

      And also are there any other things I need to know to get a career in Web Development?

      Yes, there are many, many more things to know to have a career in web development – but just making a few websites and projects is enough to get you started.

      • reachsan91 says:

        Thanks for a quick reply Tania. Can you be a little more specific in your suggestion please?
        It would help me very much, I’m desperate to learn whatever you suggest and even more desperate to find a job.
        I really appreciate your help, thanks again.

      • Tania says:

        Web development is a huge field, which is what makes it hard to be specific. For my own personal experience, I made websites about things that interested me, and learned a lot in the process. I think that’s the only real way to properly learn webdev – just start doing it. To get my first job, after I made a few sites for fun I went online and looked for freelancing opportunities to make small, one-page websites that didn’t require any programming language knowledge. I would just look up “things I need to know to become a web developer” and read some articles, and continue reading tutorials and creating things.

        Here is a resource that might help.

  • Feldrok says:

    Hello, thank you very much for the article. I understand how that first I should set the layout with bootstrap and after that just add the css… I was struggling with the fact of how should I start…

    Also, could you give me some advice with a good off-canvas menu for desktop and mobile?

    Please also add your twitter if you have 🙂

    • Feldrok says:

      Just found your twitter, nvm. Haha 😛

      • Tania says:

        Since Bootstrap doesn’t have a built in off canvas navigation that I know of, I would recommend reading an article such as this one to learn how to make that type of nav, then build the rest of your site in Bootstrap if you wish.

  • Rosie says:

    Thanks so much for writing this Tania. I’m a complete Bootstrap novice, and this provided clear and easy-to-follow instructions for me to make a start.

  • Santiago says:

    Nice and detailed article for novices, like me, thanks
    I wonder if you have opinion about singularity-gs (a grid system) and how it compares to Bootstrap. In fact looks like singularity might be nice, but it is rarely used.


    • Tania says:

      Santiago, there are a lot of grid systems that all have their pros and cons. The big thing about Bootstrap is that it’s pretty much all in one – grid, styling, typography, JavaScript, and so on. Singularity is simply a grid, so you’ll still have to do all the other stuff by hand or with another framework.

  • Skelly says:

    Thanks for the nice article, but a faster way for me to get started is using a playground like Bootply to prototype and explore different Bootstrap classes and components.

  • Umar says:

    Thank you ! Thank you !! I got to understand the bootstrap framework and how to use it with this article !

    If you can do a series of this – it might enable your readers to become pro at it

    The most to the point, clear and simple tutorial about bootstrap on the Internet !

    I will be creating a very small (3page) website with the help of this tutorial soon

    Many thanks again Tania !

    Thank you

  • Yasin inat says:

    By far the best how-to-start document, i have read about bootstrap. Thank you. Can i ask your permission to translate it to Turkish? With the your name as reference of course.

  • Zach says:

    Great article. I have just started learning HTML and CSS and have tried my hand at designing some pages.

    However, where I find myself getting stuck at is creating new designs from scratch (even with the help of Bootstrap).

    I have a certain design in mind, but I have a hard time writing the ‘structure’ of it such that it also is mobile responsive. I feel like maybe I dont really understand the fundamentals of design yet.

    Any advice?

    • Tania says:

      Well, I would definitely look at the fundamentals of responsive design post if you want to learn more about how responsive design works. It’s actually a pretty short read. It’s hard to give broad advice, but if there’s something in specific you wish to understand I can definitely help you out.

      Just think that every container is always 100% width on mobile, and on desktop that transforms with @media queries. So if you have a three column grid, it’s just three containers that are full width on mobile and 33% width on desktop.

      If you have any specific questions, let me know!
