Day 23 禁用CSS  Disable CSS 为什么 ? CSS,层叠样式表,是用来定义web页面布局和显示的机制.通过修改CSS样式,可以改变整个页面的外观. 但是有一些人,因为之前的选择或者其他原因,或选择禁用浏览器的CSS.这样可以使得站点看起来更加简单,最终也有利于屏幕阅读功能访问这些页面. 因此,在css禁用场景下的测试还是很重要的.如果禁用了CSS,你会惊讶的发现站点的流程和顺序都会有改变. 怎么做 ? 我发现的最简单的测试方法就是,用装有web开发工具插件的Firefox来打…

这里面说到的一个就是使用循环新建一个字符串时,用到了join(),这个比较高效,常常会随着push(); 绑定某个动作时,可以把要执行的绑定内容定义为一个函数,然后再执行.这样做的好处有很多.第一是可以多次执行,第二是方便调试,第三是方便重构. As a follow-up to “30 HTML and CSS Best Practices”, this week, we’ll review JavaScript! Once you’ve reviewed the list, be sure…
