What is Bootstrap?

There are a lot of questions here related to Bootstrap. I see a lot of people using it. So I tried to research it, and I found the official Bootstrap site, but there was only a download section and a few words after that. Nothing that explains what is it for... I just understood that it is a front-end helper. I have tried to find something by Googling, but found nothing specific. Everything I found is related to the computer science definition.

So, my questions are:

  • What is Bootstrap at all?
  • What is it used for, and how does it help front-end development?
  • I would also like some more details explaining it.

  • It is an HTML, CSS, javascript framework that you can use as a basis for creating web sites or web applications.

  • More information and links to download

  • Getting started

  • Examples

  • Themes

  • Bootply - Bootstrap Editor and Builder

  • Update

    The official boostrap website is updated and includes a clear definition.

    "Bootstrap is the most popular HTML, CSS, and JS framework for developing responsive, mobile first projects on the web."

    "Designed and built with all the love in the world by @mdo and @fat."


    Bootstrap is an open-source JavaScript framework developed by the team at Twitter. It is a combination of HTML , CSS , and JavaScript code designed to help build user interface components. Bootstrap was also programmed to support both HTML5 and CSS3 .

    Also it is called Front-end-framework.

    Bootstrap is a free collection of tools for creating a websites and web applications.

    It contains HTML and CSS-based design templates for typography, forms, buttons, navigation and other interface components, as well as optional JavaScript extensions.

    Some Reasons for programmers preferred Bootstrap Framework

  • Easy to get started

  • Great grid system

  • Base styling for most HTML elements(Typography,Code,Tables,Forms,Buttons,Images,Icons)

  • Extensive list of components

  • Bundled JavaScript plugins

  • Taken from About Bootstrap Framework


    Bootstrap, as I know it, is a well defined CSS. Although using Bootstrap you could also use JavaScript, jQuery etc. But the main difference is that, using Bootstrap you can just call the class name and then you get the output on the HTML form. for eg. coloring of buttons shaping of text, using layouts. For all this you do not have to write a CSS file rather you just have to use the correct class name for shaping your HTML form.
