CSS url() 函数：浏览器支持
我在 引用 url() 的值真的有必要吗？ 和 < a href="https://stackoverflow.com/questions/851724/css-background-image-what-is-the- Correct-usage">CSS 背景图像 - 正确的用法是什么？ IE 5 不支持 url() 函数内的引号。
而且 PPK 的 CSS 页面根本没有提到 url() 函数： http://www.quirksmode.org/css/contents.html
所以我会想知道浏览器对该功能的支持情况如何。哪些浏览器可以识别该值，哪些浏览器需要哪些引号、空格等等。
我意识到过去五年发布的所有内容可能都支持所有语法。我正在考虑的是较旧的浏览器。
I have seen in the comments of Is quoting the value of url() really necessary? and CSS background-image - What is the correct usage? that Mac IE 5 does not support quotation marks inside the url() function.
Also PPK's CSS page does not mention the url() function at all:
http://www.quirksmode.org/css/contents.html
So I would like to know what browser support is like for this function. What browsers recognise the value, which ones require what quotation marks, whitespace, and so on.
I realise that everything released in the past five years probably support all syntaxes. It's the older browsers I am thinking of.

Mac IE5？严肃的？ :) 我认为这个浏览器已经严重过时并且不再使用 :)
无论如何，根据 W3C，它是
body {background-image:url('paper.gif');}它适用于所有（较旧的）浏览器。如果您需要对这种古老浏览器的支持，您正在为谁开发？
Mac IE5? Serious? :) I think this browser is seriously outdated and not being used anymore :)
Anyhow, according to W3C, it's
body {background-image:url('paper.gif');}And it works for all (older) browsers. For who are you developing if you need support for this kind of ancient browsers?
对于任何浏览器类型，我从未遇到过任何背景图像问题。
当然，除非您将其作为没有内容的 div 且未指定元素的宽度和高度...

I have never ever had any issues with background-image for any browser type.
Unless of course you are putting it as a div with no content and not specifying the width and hight of the element...
