## 深阅读 **CSS coding techniques** [https://hacks.mozilla.org/2016/05/css-coding-techniques/](https://hacks.mozilla.org/2016/05/css-coding-techniques/) In this article we will see some tips and recommendation to write better, easier-to-maintain CSS code, so your stylesheets are shorter and have fewer rules. CSS can feel like a handy tool instead of a burden. **[译]Houdini：CSS 领域最令人振奋的革新** [https://zhuanlan.zhihu.com/p/20939640](https://zhuanlan.zhihu.com/p/20939640) 放 CSS 的 API 给开发者，开发者可以通过这套接口自行扩展 CSS，并提供相应的工具允许开发者介入浏览器渲染引擎的样式和布局流程中。提供了扩展 CSS 的能力，看起来很不错。 **Refactoring a javascript video store** [http://martinfowler.com/articles/refactoring-video-store-js/](http://martinfowler.com/articles/refactoring-video-store-js/) The simple example of calculating and formatting a bill for a video store opened my refactoring book in 1999\. If done in modern Javascript, there are several directions you could take the refactoring. I explore four here: refactoring to top level functions, to a nested function with a dispatcher, using classes, and transformation using an intermediate data structure. **How to Write Maintainable JavaScript** [https://www.sitepoint.com/write-maintainable-javascript/](https://www.sitepoint.com/write-maintainable-javascript/) I’ve had to take over and clean-up a lot of projects. There haven’t been many I started from scratch. In fact, I am currently doing exact that. I’ve learned a lot regarding JavaScript, keeping a codebase organised and — most importantly — not being mad at the previous developer. In this article I want to show you my steps and tell you my experience. **Building for Billions** [https://developers.google.com/billions/](https://developers.google.com/billions/) Google 推出的 Android 及 Web 大流量产品优化建议 **Creating A Living Style Guide: A Case Study** [https://www.smashingmagazine.com/2016/05/creating-a-living-style-guide-case-study](https://www.smashingmagazine.com/2016/05/creating-a-living-style-guide-case-study) Living style guides are an important tool for web development today, especially in large, complex web applications. They help document styles and patterns, keep designers and developers in sync, and greatly help to organize and distill complex interfaces. Indeed, living style guides remain one of the best ways to communicate design standards to an organization. **Don’t blame the framework: my experience with AngularJS and ReactJS** [https://www.ckl.io/blog/dont-blame-the-framework-angularjs-and-reactjs/](https://www.ckl.io/blog/dont-blame-the-framework-angularjs-and-reactjs/) For the long term, I, personally, would choose React, using Redux architecture, Axios for promise-ready HTTP requests and react-router. But it also depends on the team experience: if there’s a dedicated person for writing HTML and CSS, I would go with Angular for sure. Both of them have pros and cons and what still counts the most for a maintainable project is the developers’ commitment to write good and organized code. **理解CSS3 max/min-content及fit-content等width值** [http://www.zhangxinxu.com/wordpress/2016/05/css3-width-max-contnet-min-content-fit-content/](http://www.zhangxinxu.com/wordpress/2016/05/css3-width-max-contnet-min-content-fit-content/) 介绍了在CSS3的世界里，width 相关的这几个关键字成员。 **Enabling HTTP/2 for Dropbox web services: experiences and observations** [https://blogs.dropbox.com/tech/2016/05/enabling-http2-for-dropbox-web-services-experiences-and-observations/](https://blogs.dropbox.com/tech/2016/05/enabling-http2-for-dropbox-web-services-experiences-and-observations/) Dropbox 迁移到 HTTP/2 的经验，由于 header 压缩，流入带宽降了居然有 50%，这得有多少 cookie 啊 **简单易懂的CSS Modules** [http://mp.weixin.qq.com/s?__biz=MjM5MTA1MjAxMQ==&mid=2651220796&idx=1&sn=4099912162d73a3a39c62e8f62a7fd89](http://mp.weixin.qq.com/s?__biz=MjM5MTA1MjAxMQ==&mid=2651220796&idx=1&sn=4099912162d73a3a39c62e8f62a7fd89) 科普 CSS Modules。感觉 HTML CSS DOM 正在被变成底层语言。 **我是这样学习前端的** [https://github.com/icepy/_posts/issues/39](https://github.com/icepy/_posts/issues/39) 写总结挺重要的 **ES2015实战——面向未来编程** [http://yanhaijing.com/javascript/2016/04/27/es2015-practice/](http://yanhaijing.com/javascript/2016/04/27/es2015-practice/) 总结了近一年时间对ES6的使用，实践，思考。作者一开始对 ES6 是拒绝的，后来的经历和思考发生了转变。文艺范十足的科普文。 **为什么我们应该尽快支持 ALPN** [https://ma.ttias.be/day-google-chrome-disables-http2-nearly-everyone-may-31st-2016/](https://ma.ttias.be/day-google-chrome-disables-http2-nearly-everyone-may-31st-2016/) [https://imququ.com/post/enable-alpn-asap.html](https://imququ.com/post/enable-alpn-asap.html) Google 将于本月底正式发布的 Chrome 51，又一次禁用 SPDY 和 NPN，还是赶紧升级到 HTTP/2 和 ALPN（需 OpenSSL 1.0.2+）吧！ **JSON Patch and JSON Merge Patch** [http://erosb.github.io/post/json-patch-vs-merge-patch/](http://erosb.github.io/post/json-patch-vs-merge-patch/) 对比了这两个 JSON patch 的方案 **An overview of realtime libraries and frameworks** [https://deepstream.io/blog/realtime-framework-overview/](https://deepstream.io/blog/realtime-framework-overview/) 整理了现有的试试库及框架 **记一次惊心动魄的前端性能优化之旅** [https://segmentfault.com/a/1190000005147979](https://segmentfault.com/a/1190000005147979) 某产品从原生切换到 Hybird 后遇到性能问题，来看看作者是如何解决的 **5 JavaScript “Bad” Parts That Are Fixed In ES6** [https://medium.com/@rajaraodv/5-javascript-bad-parts-that-are-fixed-in-es6-c7c45d44fd81#.e8oswtpcf](https://medium.com/@rajaraodv/5-javascript-bad-parts-that-are-fixed-in-es6-c7c45d44fd81#.e8oswtpcf) ECMAScript 6 (ES6) features can be divided into features that are pure syntactic sugar (like: class), features that enhance JavaScript (like import) and features that fix some of JS’s “bad” parts (like let keyword). Most blogs and articles combine all 3 types and can overwhelm new comers. So I am writing a blog that talks about just the features that fix “bad” parts. **Reducing JPG File size** [https://medium.com/@duhroach/reducing-jpg-file-size-e5b27df3257c](https://medium.com/@duhroach/reducing-jpg-file-size-e5b27df3257c) While JPG compression is impressive in its’ own right, how you use it in your application can influence the size of these files significantly.

The 1.12 and 2.2 branches will continue to receive critical support patches for a while, but will not get any new features or major revisions. Note that jQuery 3.0 will not support IE6-8\.
