Bootstrap v4.0.0-beta.2 发布了，Bootstrap是快速开发Web应用程序的前端工具包。它是一个CSS和HTML的集合，它使用了最新的浏览器技术，给你的Web开发提供了时尚的版式，表单，buttons，表格，网格系统等等。 此次更新的亮点有： Improved Sass map customization with #23260. With this change, it's now possible to override specific key value pairs instead of resetting the entire map, ideal for color scheme customization. Restored grid .offset- modifiers in #23445. Originally our intent was to supplement this with our margin utilities, but we underestimated the appeal of fixed number column offsets. Remove unnecessary color from .badge, and it's associated $badge-color variable, in #23529. Rename grayscale function to gray to avoid breaking CSS native grayscale filter in #23579. Renamed .table-inverse, .thead-inverse, and .thead-default to .*-dark and .*-light, matching our color schemes used elsewhere in #23560. Responsive tables now generate classes for each grid breakpoint, meaning we've added .table-responsive-{sm,md,lg,xl} to the already present .table-responsive. You might need to adjust your usage depending on when you want a table to resize. See #22804. Include two new dist files which contain Popper.js inside bootstrap.bundle.js and bootstrap.bundle.min.js. See #23735. Dropped support for Bower as they've deprecated the package manager. See #23568. Switched breadcrumbs from float to flexbox in #23683. Added new CSS variables in #23761. Switched to Stylelint in #23572. New Theming page in the docs from #23611 #23943: Changed the color-yiq from a mixin that included the color property to a function that returns a value, allowing you to use it for any CSS property. For example, instead of color-yiq(#000), you'd write color: color-yiq(#000);. New and improved theming in #24429. 完整内容请查看。 下载地址： bootstrap-4.0.0-beta.2-dist.zip Source code (zip) Source code (tar.gz) Bootstrap v4.0.0-beta.2 发布，Web 前端 UI 框架下载地址
