Should the reference to the Modernizr JavaScript file be in the head of the page? I always try and place all scripts on the bottom of the page and would like to preserve this. And if it needs to be in the head, why?
推荐答案
如果要 Modernizr 下载并尽快执行以防止 FOUC ，将其放入<head>
If you want Modernizr to download and execute as soon as possible to prevent a FOUC, put it in the <head>
摘自他们的安装指南:
将脚本标签放到
<head>的 您的HTML.为了获得最佳性能，您 应该让他们跟随你的 样式表参考.我们之所以 建议将Modernizr放在 头有两个方面:HTML5 Shiv(即 必须在IE中启用HTML5元素) 在<body>之前执行，如果 您正在使用任何CSS类 加上Modernizr，您将想要 防止FOUC.
Drop the script tags in the
<head>of your HTML. For best performance, you should have them follow after your stylesheet references. The reason we recommend placing Modernizr in the head is two-fold: the HTML5 Shiv (that enables HTML5 elements in IE) must execute before the<body>, and if you’re using any of the CSS classes that Modernizr adds, you’ll want to prevent a FOUC.
