Bootstrap4 首個(gè)Beta版發(fā)布：距上次發(fā)布已7月之久！

北京時(shí)間2017年8月12日，Bootstrap 4 的首個(gè) Beta 版終于發(fā)布了。此次Beta版本距離上次發(fā)布 4.0 的最后一個(gè) alpha 版已經(jīng)過(guò)去了 7 個(gè)月。

該版本取消將 Normalize.css 作為依賴關(guān)系，而是 fork 其中的一部分并和 Bootstrap 自家的 Reboot 混合，以獲得更穩(wěn)定的標(biāo)準(zhǔn)化方法。還對(duì)導(dǎo)航、網(wǎng)格進(jìn)行了改進(jìn)以及對(duì) Flexbox 進(jìn)行一些兼容性的處理。

此外，該版本將 jQuery 和 Popper 移動(dòng)到了 peerDependencies ，因?yàn)樗鼈儾皇?Bootstrap 每個(gè)部分所要求的。往下閱讀更多的更新內(nèi)容。

值得關(guān)注的更新：

• Dropped Normalize.css as a dependency, forking some of it and remixing it with our own Reboot for a more stable normalization approach.
• Update navbar responsive behaviors to be mobile first, use a new class name .navbar-expandinstead of .navbar-toggleable, remove toggler position modifiers (relies on flex utils now), and fix a handful of bugs.
• Stabilize some grid behaviors and update the docs.
• Updated the grid to drop push, pull, and offset in favor of new .order- modifiers and margin utilities.
• Renamed tons of variables (see #22414 and #22092) for a more consistent naming scheme.
• Removed remaining cursor: pointers to restore browser defaults and better indicate actions vs hyperlinks.
• Renamed flexbox order utilities to better match utility naming scheme of .property-value.
• Restored Alpha 5's placement of _custom.scss in our import order.
• Rewrote display and responsive utilities to de-dupe a bunch of functionality.
• Removed Gruntfile and docs from package manager builds.
• Overhauled our color system with new Sass maps, variables, classes, and component variants.
• Updated browser support to bring ranges up to more recent versions.
• Added a bash script for linting unused variables.
• Moved jQuery and Popper to peerDependencies as they're not requirements for every part of Bootstrap.
