Luckily, Bootstrap comes with comprehensive documentation, so it’s easy to look up how each bit of code works in detail. The documentation even includes samples of code, making it easier for beginners to pick up Bootstrap.
Get a jump on including Bootstrap’s source files in a new project with our official guides. When you only need to include Bootstrap’s compiled CSS or JS, you can use jsDelivr. See it in action with our simple quick start, or browse the examples to jumpstart what is bootstrap used for your next project. Jump right into building with Bootstrap—use the CDN, install it via package manager, or download the source code. For more straightforward sizing in CSS, we switch the global box-sizing value from content-box to border-box.
Responsive tables
A handful of variables for quickly customizing key elements of your site’s skeleton. Variables are used throughout the entire project as a way to centralize and share commonly used values like colors, spacing, or font stacks. Easily clear floats by adding .clearfix to the parent element. Utilizes the micro clearfix as popularized by Nicolas Gallagher. Use any of the available button classes to quickly create a styled button.
JQuery is needed for Bootstrap plugins and needs to load before bootstrap.js. If you aren’t using any of Bootstrap’s interactive features, you can omit these files from the source. A powerful collection of HTML, CSS, and JavaScript tools, it makes responsive web development easy. Bootstrap Icons is an open source SVG icon library featuring over 1,800 glyphs, with more added every release.
Available classes
The mixins are deprecated as of v3.2.0, with the introduction of Autoprefixer. To preserve backwards-compatibility, Bootstrap will continue to use the mixins internally until Bootstrap v4. Set all transition information with one, or specify a separate delay and duration as needed. The mixin is deprecated as of v3.1.0, since Bootstrap doesn’t officially support the outdated platforms that don’t support the standard property. To preserve backwards-compatibility, Bootstrap will continue to use the mixin internally until Bootstrap v4.
There are also predefined styles for block quotes, and unordered and ordered lists, with inline options, to name a few. Beginning developers often assume their pure and unstyled HTML will look the same across all browsers. Unfortunately, every browser has its own default “user agent” style sheet applied to the HTML, and no two browsers have the same defaults. To address all these inconsistencies, different CSS “reset” rules define consistent style defaults. These Bootstrap templates are available as well-factored CSS classes that you can apply to HTML to achieve different effects.
responsive Layout Component__ the Grid System.
Be sure to use rgba() colors in your box shadows so they blend as seamlessly as possible with backgrounds. If your target audience is using the latest and greatest browsers and devices, be sure to just use the box-shadow property on its own. If you need support for older Android (pre-v4) and iOS devices (pre-iOS 5), use the deprecated mixin to pick up the required -webkit prefix. Easily set your typeface, text size, leading, and more with a few quick variables. Bootstrap makes use of these as well to provide easy typographic mixins.
As CSS became more mature, a number of CSS frameworks for grid-based layouts started to appear. Using color to add meaning only provides a visual indication, which will not be conveyed to users of assistive technologies – such as screen readers. Using color to add meaning to a button only provides a visual indication, which will not be conveyed to users of assistive technologies – such as screen readers. Developers often override or customize default Bootstrap CSS styles when working on web development projects.
Bootstrap 5 Other
With the four tiers of grids available you’re bound to run into issues where, at certain breakpoints, your columns don’t clear quite right as one is taller than the other. To fix that, use a combination of a .clearfix and our responsive utility classes. With Bootstrap 2, we added optional mobile friendly styles for key aspects of the framework. With Bootstrap 3, we’ve rewritten the project to be mobile friendly from the start.
It is possible to disable page responsiveness completely on older Bootstrap versions. For a container that is not responsive, that means a width of 970px. Also, in this case, navbars won’t collapse in mobile views, as we’ll describe later. To use the Bootstrap grid system, you must follow certain rules. Grid column elements are placed inside row elements, which create horizontal groups of columns.
You can also install Bootstrap with a package manager ‒ a tool that manages and updates frameworks, libraries, and assets. With our online editor, you can edit the code, and click on a button to view the result. It is important to start any HTML with an HTML 5 Doctype declaration so that browsers know what kind of a document toexpect. The head contains three important tags that must be declared first, and any additional head tags must be added after these.
- This is exactly why the custom.css reference should follow after Bootstrap.css.
- Bootstrap uses icons called Glyphicons, which include a Glyphicons Halflings set.
- Bootstrap is a powerful tool that lets you quickly build attractive websites that look great on desktops, phones, and tablets.
- Note that, due to padding and more, neither container is nestable.
Otherwise, all websites built with this framework will have the same navigation, structure, and design components, making them look unprofessional. One of the reasons why Bootstrap is so popular among web developers and web designers is that it has a simple file structure. Its files are compiled for easy access, and it only requires basic knowledge of HTML, CSS, and JS to modify them. For example, the “source code” version of Bootstrap lets you access the Sass port. This means it creates a custom stylesheet that imports Bootstrap, allowing you to modify and extend the tool as needed. Bootstrap’s primary objective is to create responsive, mobile-first websites.

They’re designed to work in any project, whether you use Bootstrap itself or not. Use them as SVGs or icon fonts—both options give you vector scaling and easy customization via CSS. Use Bootstrap’s utility API to modify any of our included utilities or create your own custom utilities for any project. Import Bootstrap first, then use Sass map functions to modify, add, or remove utilities. Get more advanced and set a direction, use three colors, or use a radial gradient. With a single mixin you get all the prefixed syntaxes you’ll need.
