Bootstrap is a free and open-source CSS framework directed at responsive, mobile-first front-end web development. It contains CSS- and JavaScript-based design templates for typography, forms, buttons, navigation, and other interface components.

Bootstrap was created by Mark Otto and Jacob Thornton at Twitter, and is now used by more than 12 million websites. Bootstrap is open source and available on GitHub.

Why do web developers love using Bootstrap?

Bootstrap is the most popular HTML, CSS, and JavaScript framework for developing responsive, mobile-first websites. Bootstrap is completely free to download and use.

Web developers love Bootstrap because it helps them create responsive websites faster and easier. Bootstrap is a front-end framework that includes pre-built CSS and JavaScript components that are easy to use and customize.

Bootstrap is free and open source, which makes it a great choice for developers who want to create responsive websites on a budget.

Bootstrap is easy to use. You just need to include the Bootstrap CSS and JS files in your HTML code. Bootstrap is also available as a Sass and Less files.

Bootstrap's responsive grid

Bootstrap also gives you the ability to easily create responsive designs. Responsive design is a method of web development that makes your web pages look good on all devices (desktops, laptops, tablets, and phones).

Bootstrap's responsive grid system is based on a 12-column grid, with a gutter of 30px (15px on each side of a column).

The Bootstrap grid system is responsive, and the columns will re-arrange depending on the screen size:

On a large screen, the column layout will be: col-lg-*

On a medium screen, the column layout will be: col-md-*

On a small screen, the column layout will be: col-sm-*

On an extra small screen, the column layout will be: col-xs-*

The * represents the number of columns out of 12 that the column should span. So, for example, if you want a column to span 8 columns on a large screen, you would use: col-lg-8

If you want the column to span 4 columns on a medium screen, you would use: col-md-4

Bootstrap's components

Bootstrap's components can be divided into three categories: layout, content, and components.

Layout components are responsible for the overall structure of the web page. They include the grid system, which is used to create responsive layouts, and the media object, which is used to create responsive images and videos.

Content components are responsible for the content of the web page. They include the typography, which is used to style the text, and the tables, which are used to display tabular data.

Components are responsible for the interactive elements of the web page. They include the buttons, which are used to trigger actions, and the modals, which are used to display information in a popup window.
