What is Bootstrap?

In 2010, Twitter needed a library in which the design includes uniform for different interfaces of web pages. From this idea, a framework was created in 2011, which was published as an open source project and is now widely used in its fifth version.

Bootstrap is a free and open source front-end web framework for building websites. It is for front-end development only and includes HTML and CSS-based design templates for typography, forms, buttons, and navigation, as well as optional JavaScript extensions. The result is a consistent look and feel across web browsers. In addition, developers can use the CSS classes defined in Bootstrap to further customize the appearance of their content.

JavaScript modules make it possible to include user interactions, such as dialog boxes, image slideshows, and tabs. Bootstrap also offers all the prerequisites for responsive web design, so that websites are optimally displayed on all devices (desktop, smartphones and tablets).

Bootstrap provides individual components that you can insert into your website. Each component consists of an HTML structure, CSS declarations, and in some cases, accompanying JavaScript code.

Bootstrap uses a superset of CSS, the stylesheet language Sass (Syntactically Awesome Stylesheets). Modular in design, Bootstrap 4 is divided into layout, content, bootstrap profile, components and tools. The developer can specify which components of these he wants to use.
