Bootstrap
Bootstrap, a front-end toolkit for rapidly developing web applications. It is a collection of CSS and HTML conventions. It uses some of the latest browser techniques to provide you with stylish typography, forms, buttons, tables, grids, navigation and everything else you need in a super tiny resource
Why use Bootstrap
Bootstrap is just CSS, but it’s built with Less, a flexible pre-processor that offers much more power and flexibility than regular CSS. With Less, we gain a range of features like nested declarations, variables, mixins, operations, and color functions. Additionally, since Bootstrap is purely CSS when compiled via Less, we gain two important benefits:
First, Bootstrap remains very easy to implement; just drop it in your code and go. Compiling Less can be accomplished via Javascript, an unofficial Mac application, or via Node.js (read more about this at http://lesscss.org).
Second, once complied, Bootstrap contains nothing but CSS, meaning there are no superfluous images, Flash, or Javascript. All that remains is simple and powerful CSS for your web development needs.
What’s inside
When you take a closer look at Bootstrap, you will notice we have separated the development files into seven distinct files:
reset.less A CSS reset originally made by Eric Meyer and modified for our use to remove unnecessary elements
preboot.less Color variables and mixins for things like gradients, transparencies, and transitions to simplify vendox-prefixed CSS blocks to one line of code each
scaffolding.less Basic and global styles for generating a grid system, structural layout, and page templates
type.less Headings, body text, lists, code, and more for a versatile and durable typography system
patterns.less Repeatable interface elements like navigation, modals, popovers, and tooltips to take you beyond the default scaffolding styles
forms.less Durable styles for various input types, form layouts, and control states.
tables.less Styles for tabular data in a number of varied displays
Since we opted to break our CSS into more manageable chunks for easy organization and iterations, compiling these files with Less means you end up with just one CSS file to include.
Why it works
Bootstrap works by providing a clean and uniform solution to the most common, everyday interface tasks developers come across. At Twitter, Bootstrap has quickly become one of our many go-to front-end tools when starting new applications and sites. This is because while it is very extensive, it’s flexible enough to work for many unique design needs.
Today, you can use Bootstrap to throw together quick prototypes or guide the execution of more sophisticated designs and larger engineering efforts. In other words, Bootstrap is a very simple way to promote quick, clean and highly usable applications.
We look forward to working with the open source community to evolve Bootstrap.
Where Bootstrap is heading
We want to keep working on slimming down Bootstrap’s already tiny footprint while also increasing the breadth of what it covers. As always, we’d love your feedback and hope you find it useful. If you’d like to help make Bootstrap better, feel free to fork it, file issues and watch its progress over on GitHub.
