What is Bootstrap?

Bootstrap is a free, open-source CSS framework that gives you a collection of ready-made buttons, navigation bars, grids, forms, and other building blocks you can drop straight into your HTML. Instead of writing CSS from scratch every time you start a new project, Bootstrap lets you apply pre-built styles by adding class names to your HTML elements.

Bootstrap was originally created by developers at Twitter and has become one of the more popular front-end frameworks over time. It's a good option for building responsive websites quickly without spending a ton of extra time writing components and styles from scratch.

Why learn Bootstrap?

Because Bootstrap handles so much of the styling and layout work for you, picking it up can help you focus on how websites are structured without getting bogged down in complex CSS. There's a large community around Bootstrap and lots of documentation, tutorials, and forums to help you get started.

Bootstrap has also been widely adopted over the years, so having it as a skill can be a great thing to add to your resume since lots of websites and companies rely on it today.

Practice Bootstrap on Frontend Mentor

Learning Bootstrap by reading articles or watching videos about it is useful, but actually using it on a real project is where things start to click. Frontend Mentor gives you realistic, professionally designed projects to build, so you can practice using Bootstrap like you would in the real world.

Each challenge comes with design files and assets so you can focus on writing the code rather than making decisions about colors and layouts, and you'll be able to reach out to our community of learners who are learning to code by building projects as well.
