Вступление
Начните работу с Bootstrap, самой популярной в мире платформой для создания адаптивных сайтов, ориентированных на мобильные устройства, с jsDelivr и начальной страницей шаблона.
Быстрый старт
Хотите быстро добавить Bootstrap в свой проект? Используйте jsDelivr, бесплатный CDN с открытым исходным кодом. Используете менеджер пакетов или Вам нужно скачать исходные файлы? Перейдите на страницу загрузок.
Скопируйте и вставьте таблицу стилей
в Ваш перед всеми остальными таблицами стилей, чтобы загрузить наш CSS.
Многие из наших компонентов требуют использования JavaScript для работы. В частности, для них требуются jQuery, Popper и наши собственные плагины JavaScript. Мы используем тонкую сборку jQuery, но также поддерживается полная версия.
Поместите один из следующих —> body > html >
Это все, что Вам нужно для выполнения общих требований к странице. Посетите Документацию по макету или наши официальные примеры, чтобы начать размещение содержимого и компонентов Вашего сайта.
Глобально важно
Bootstrap использует несколько важных глобальных стилей и настроек, о которых Вам необходимо знать при его использовании, и все они почти исключительно нацелены на нормализацию кроссбраузерных стилей. Давайте погрузимся.
HTML5 doctype
Bootstrap требует использования документа типа HTML5. Без него Вы увидите несколько забавных неполных стилей, но его включение не должно вызывать каких-либо серьезных сбоев.
Адаптивный метатег
Bootstrap разработан как сначала мобильный, стратегия, в которой мы сначала оптимизируем код для мобильных устройств, а затем масштабируем компоненты по мере необходимости с помощью медиа-запросов CSS. Чтобы обеспечить правильный рендеринг и сенсорное масштабирование для всех устройств, добавьте метатег адаптивного окна просмотра к Вашему .
Вы можете увидеть пример этого в действии в стартовом шаблоне.
Box-sizing
Для более простого изменения размера в CSS мы переключаем глобальное значение box-sizing с content-box на border-box . Это гарантирует, что padding не влияет на окончательную вычисленную ширину элемента, но может вызвать проблемы с некоторым сторонним программным обеспечением, таким как Google Maps или Google Custom Search Engine.
В редких случаях Вам нужно отменить его, используйте что-то вроде следующего:
WiВ приведенном выше фрагменте все вложенные элементы, включая сгенерированный контент с помощью ::before и ::after , будут наследовать указанный box-sizing для этого .selector-for-some-widget .
Reboot
Для улучшения кроссбраузерности рендеринга мы используем Перезагрузку, чтобы исправить несоответствия между браузерами и устройствами, обеспечивая при этом несколько более самоуверенный сброс общих элементов HTML.
Сообщество
Будьте в курсе развития Bootstrap и обращайтесь к сообществу с помощью этих полезных ресурсов.
- Вступите в группу @getbootstrap_ru в Телеграм.
- Прочтите и подпишитесь на Официальный блог Bootstrap.
- Присоединяйтесь к официальной комнате Slack.
- Общайтесь с другими Бутстрапперами в IRC. На сервере irc.libera.chat , в канале #bootstrap .
- Справку по реализации можно найти на сайте Stack Overflow (с тегом bootstrap-4 ).
- Разработчикам следует использовать ключевое слово bootstrap в пакетах, которые изменяют или расширяют функциональность Bootstrap при распространении через npm или аналогичные механизмы доставки для максимальной доступности.
Вы также можете следить за @getbootstrap в Twitter, чтобы следить за последними сплетнями и потрясающими музыкальными клипами.
CSP и встроенные SVG
Некоторые компоненты Bootstrap включают встроенные SVG в наш CSS для единообразного и простого стиля компонентов в разных браузерах и на разных устройствах. Для организаций с более строгими конфигурациями CSP , мы задокументировали все экземпляры наших встроенных SVG (все из которых применяются через background-image ), поэтому Вы можете более тщательно изучить свои варианты.
Основываясь на обсуждениях сообщества, некоторые варианты решения этой проблемы в Вашей собственной кодовой базе включают замену URL-адресов локально размещенными ресурсами, удаление изображений и использование встроенных изображений ( невозможно во всех компонентах) и изменение вашего CSP. Наша рекомендация — внимательно изучить свои собственные политики безопасности и при необходимости выбрать лучший путь для дальнейшего развития.

Download
Download Bootstrap to get the compiled CSS and JavaScript, source code, or include it with your favorite package managers like npm, RubyGems, and more.
Compiled CSS and JS
Download ready-to-use compiled code for Bootstrap v5.0.2 to easily drop into your project, which includes:
- Compiled and minified CSS bundles (see CSS files comparison)
- Compiled and minified JavaScript plugins (see JS files comparison)
This doesn’t include documentation, source files, or any optional JavaScript dependencies like Popper.
Source files
Compile Bootstrap with your own asset pipeline by downloading our source Sass, JavaScript, and documentation files. This option requires some additional tooling:
- Sass compiler for compiling Sass source files into CSS files
- Autoprefixer for CSS vendor prefixing
Should you require our full set of build tools, they are included for developing Bootstrap and its docs, but they’re likely unsuitable for your own purposes.
Examples
If you want to download and examine our examples, you can grab the already built examples:
CDN via jsDelivr
Skip the download with jsDelivr to deliver cached version of Bootstrap’s compiled CSS and JS to your project.
If you’re using our compiled JavaScript and prefer to include Popper separately, add Popper before our JS, via a CDN preferably.
Package managers
Pull in Bootstrap’s source files into nearly any project with some of the most popular package managers. No matter the package manager, Bootstrap will require a Sass compiler and Autoprefixer for a setup that matches our official compiled versions.
Install Bootstrap in your Node.js powered apps with the npm package:
const bootstrap = require(‘bootstrap’) or import bootstrap from ‘bootstrap’ will load all of Bootstrap’s plugins onto a bootstrap object. The bootstrap module itself exports all of our plugins. You can manually load Bootstrap’s plugins individually by loading the /js/dist/*.js files under the package’s top-level directory.
Bootstrap’s package.json contains some additional metadata under the following keys:
- sass — path to Bootstrap’s main Sass source file
- style — path to Bootstrap’s non-minified CSS that’s been precompiled using the default settings (no customization)
Install Bootstrap in your Node.js powered apps with the yarn package:
RubyGems
Install Bootstrap in your Ruby apps using Bundler (recommended) and RubyGems by adding the following line to your Gemfile :
Alternatively, if you’re not using Bundler, you can install the gem by running this command:
Composer
You can also install and manage Bootstrap’s Sass and JavaScript using Composer:
NuGet
If you develop in .NET, you can also install and manage Bootstrap’s CSS or Sass and JavaScript using NuGet:

Introduction
Get started with Bootstrap, the world’s most popular framework for building responsive, mobile-first sites, with jsDelivr and a template starter page.
Quick start
Looking to quickly add Bootstrap to your project? Use jsDelivr, a free open source CDN. Using a package manager or need to download the source files? Head to the downloads page.
Copy-paste the stylesheet
into your before all other stylesheets to load our CSS.
Many of our components require the use of JavaScript to function. Specifically, they require our own JavaScript plugins and Popper. Place one of the following —> body > html >
For next steps, visit the Layout docs or our official examples to start laying out your site’s content and components.
Important globals
Bootstrap employs a handful of important global styles and settings that you’ll need to be aware of when using it, all of which are almost exclusively geared towards the normalization of cross browser styles. Let’s dive in.
HTML5 doctype
Bootstrap requires the use of the HTML5 doctype. Without it, you’ll see some funky incomplete styling, but including it shouldn’t cause any considerable hiccups.
Responsive meta tag
Bootstrap is developed mobile first, a strategy in which we optimize code for mobile devices first and then scale up components as necessary using CSS media queries. To ensure proper rendering and touch zooming for all devices, add the responsive viewport meta tag to your .
You can see an example of this in action in the starter template.
Box-sizing
For more straightforward sizing in CSS, we switch the global box-sizing value from content-box to border-box . This ensures padding does not affect the final computed width of an element, but it can cause problems with some third-party software like Google Maps and Google Custom Search Engine.
On the rare occasion you need to override it, use something like the following:
With the above snippet, nested elements—including generated content via ::before and ::after —will all inherit the specified box-sizing for that .selector-for-some-widget .
Reboot
For improved cross-browser rendering, we use Reboot to correct inconsistencies across browsers and devices while providing slightly more opinionated resets to common HTML elements.
Community

CSPs and embedded SVGs
Several Bootstrap components include embedded SVGs in our CSS to style components consistently and easily across browsers and devices. For organizations with more strict CSP configurations, we’ve documented all instances of our embedded SVGs (all of which are applied via background-image ) so you can more thoroughly review your options.
Based on community conversation, some options for addressing this in your own codebase include replacing the URLs with locally hosted assets, removing the images and using inline images (not possible in all components), and modifying your CSP. Our recommendation is to carefully review your own security policies and decide on a best path forward, if necessary.
