Bootstrap是一个开源的，移动优先的CSS, JavaScript和HTML设计实用程序的集合，旨在提供方法来开发常用的web元素，比从头开始编码要快得多(和更聪明)。

促成Bootstrap成功的几个核心原则:

it's reusable it's flexible (i.e: allows custom grid systems, changing responsiveness breakpoints, column gutter sizes or state colors with ease; as a rule of thumb, most settings are controlled by global variables) it's intuitive it's modular (both JavaScript and (S)CSS use a modular approach; one can easily find tutorials on making custom Bootstrap builds, to include only the parts they need) has above average cross-browser compatibility web accessibility out of the box (screenreader ready) it's fairly well documented

根据今天的标准和网络术语，我想说Bootstrap实际上不是一个框架，尽管他们的网站上是这么说的。大多数开发人员会考虑Angular、Vue和React框架，而Bootstrap通常被称为“库”。

但是，准确地说，Bootstrap是一个开源的、移动优先的CSS、JavaScript和HTML设计实用程序的集合，旨在提供比从头开始编写代码更快(也更聪明)开发常用web元素的方法。

促成Bootstrap成功的几个核心原则:

it's reusable it's flexible (i.e: allows custom grid systems, changing responsiveness breakpoints, column gutter sizes or state colors with ease; as a rule of thumb, most settings are controlled by global variables) it's intuitive it's modular (both JavaScript and (S)CSS use a modular approach; one can easily find tutorials on making custom Bootstrap builds, to include only the parts they need) has above average cross-browser compatibility web accessibility out of the box (screenreader ready) it's fairly well documented

It contains design templates and functionality for: layout, typography, forms, navigation, menus (including dropdowns), buttons, panels, badges, modals, alerts, tabs, collapsible, accordions, carousels, lists, tables, pagination, media utilities (including embeds, images and image replacement), responsiveness utilities, color-based utilities (primary, secondary, danger, warning, info, light, dark, muted, white), other utilities (position, margin, padding, sizing, spacing, alignment, visibility), scrollspy, affix, tooltips, popovers.

默认情况下，它依赖于jQuery，但你会发现jQuery免费变体由每个现代流行的渐进式JavaScript框架支持:

React-Bootstrap - React驱动的Bootstrap BootstrapVue - Vue驱动的Bootstrap ng-bootstrap——Angular支持的Bootstrap

使用Bootstrap很大程度上依赖于应用特定的类(或者，取决于JS框架:指令、方法或属性/道具)和使用特定的标记结构。

文档通常包含通用示例，这些示例可以轻松地复制粘贴并用作起始模板。

使用Bootstrap开发的另一个优势是它充满活力的社区，转化为丰富的主题、模板和插件，其中大多数是开源的(即:日历、日期/时间选择器、表格内容管理插件，以及构建在Bootstrap之上的库/组件集合，如MDB、投资组合模板、管理模板等…)

最后，但并非最不重要的是，Bootstrap多年来一直得到很好的维护，这使得它成为生产就绪应用程序/网站的可靠选择。

Bootstrap是开源的HTML框架。几乎所有浏览器都兼容。基本上大屏浏览器的宽度是>992px和特大号1200px。因此，通过使用Bootstrap定义的类，我们可以调整屏幕分辨率，以显示从小手机到大屏幕的每个屏幕上的内容。我尽量简短地解释。 例如:

<div class="col-sm-3">....</div>
<div class="col-sm-9">....</div>

它是一个HTML、CSS和JavaScript开源框架(最初由Twitter创建)，您可以使用它作为创建网站或web应用程序的基础。
