了解HTML5Shiv的Modernizr好处

Question

我知道这两个脚本库的网站上有很多好的问题。

我想问一下我似乎无法找到的东西。

modernizr 提供 html5shiv 并不从框中出来，即，只是包括脚本。

我知道html5shiv“只是”修复了IE <9的HTML5元素，它是否有支持停止？

Modernizr在IE导航器上修复CSS3问题吗？IE9.js做到了吗？（并且我的意思是出于框中的这个特殊问题，没有额外的js代码来处理角落案例）

除了包括脚本之外，您考虑到使用库时，现代化的优势是什么是HTML5Shiv？

Answer 1

They do different things.

Modernizr detects the availability of features in a page allowing you to provide your own polyfills for older browsers should you require that functionality. You can add support for <canvas> using a canvas tag polyfill so that canvas functionality, including it's JavaScript interface, in browsers that don't support the <canvas> tag.

Html5shiv adds the new html5 tags that aren't available (<section>, <header>, etc) to older browsers. It also creates the default styles (display: block for <section> for example).

That's it. It provides no other functionality.

Answer 2

Modernizr 1.5+ actually includes HTML5Shiv, so if you use it, shiv is redundant. Source: http://modernizr.com/docs/#html5inie

"As of Modernizr 1.5, this script is identical to what is used in the popular html5shim/html5shiv library."
