在打印浏览器的网页时,它是指在<代码>media=”的.cs上标的。 浏览器拆卸了诸如background-image
和background-color
等一些电流器可选择使用。
我对此有两个问题:
- Is there any documentation or good reference about these printing rules ? For example:
- Which CSS rules are disabled ?
- Can Javascript do something on the page before printing ?
- Is there a way to detect a browser in printing mode with Javascript and then make a graceful degradation system ?
