What Is Bootstrap? A Beginner’s Guide to Responsive Web Design (2026)
In July 2013 QuickOnlineTips switched to Bootstrap, the front-end framework created at Twitter, and we used its responsive grid, menus and icons all over the site. More than a decade later, Bootstrap is still one of the most popular ways to build responsive websites. So what is Bootstrap in 2026, and should you use it? Here’s a beginner guide.
Quick answer: Bootstrap is a free, open source CSS and JavaScript framework for building responsive, mobile-first websites. It gives you a 12-column grid, ready-made components (navbars, buttons, cards, modals, forms) and utility classes. Bootstrap 5 no longer needs jQuery, supports dark mode, and you can add it with one CSS link and one script tag from a CDN.
Table of Contents
What’s included in Bootstrap
- Grid system: 12 columns with breakpoints (sm, md, lg, xl, xxl) to adapt layouts to any screen.
- Components: navbar, dropdowns, cards, alerts, modals, carousels, accordions and toasts.
- Forms: consistent inputs, validation styles and floating labels.
- Utilities: spacing, colours, flexbox and display classes like
mt-3ord-flex. - Color modes: built-in light and dark themes.
- Bootstrap Icons: a separate free SVG icon library, or use Font Awesome icons in Bootstrap.
How to add Bootstrap to a page
- Add the Bootstrap CSS link in your <head>.
- Add the bundle script before </body>.
- Include
<meta name="viewport" content="width=device-width, initial-scale=1">. - Start with a container and rows:
<div class="container"><div class="row"><div class="col-md-6">...
Copy the latest CDN links from the official getbootstrap.com (external site) site.
Pros and cons
- Pros: fast prototyping, consistent design, great documentation, huge community and themes.
- Cons: sites can look alike, and unused CSS adds weight unless you customise the build with Sass.
- Alternatives: Tailwind CSS (utility-first), or tiny frameworks like Chota.

Bootstraps could really be the next big thing. Twitter do not have a lot of things to do with its advertisements because it basically looks like a one-way website. Also, it cannot get so much detail into it because they might just think it is copying from other social networking sites.
Thanks for giving insights on Bootstrap.
I should definitely use it on my next custom web design project.
i downloaded the bootstrap but how to install kindly let me know
Simply insert the lines of code into your header or footer
Because I like to work with responsive designs, the main reason why I wouldn’t use them is because I prefer to design each responsive step “separately” and as a whole. And these templates usually work with a more or less rigid grid that you can’t fully tweak.
Nice review of Boost strap. Seems interesting. I will give it a try over my blog.
