Background image resizing to fit
提问by vla
I'm trying to make the background image as professional as possible so I'm thinking it's best to resize it based on the size of the browser or the resolution (not sure what's usually used, but I think browser size makes sense here). The idea is if the viewer screen is small, the background image gets smaller, and as the screen gets bigger, the image expands to fit its maximum size.
我试图使背景图像尽可能专业，所以我认为最好根据浏览器的大小或分辨率调整它的大小（不确定通常使用什么，但我认为浏览器大小在这里有意义）。这个想法是如果查看器屏幕很小，背景图像会变小，随着屏幕变大，图像会扩展以适应其最大尺寸。
I will try a CSS or even Javascript (JQuery) solution as needed.

You will need to stick to CSS 3 background-size property to achieve this: http://webdesign.about.com/od/styleproperties/p/blspbgsize.htm
Without using CSS 3 you cannot resize the background image in any way on the client.
您需要坚持使用 CSS 3 background-size 属性来实现这一点：http: //webdesign.about.com/od/styleproperties/p/blspbgsize.htm
如果不使用 CSS 3，您将无法以任何方式调整背景图像的大小客户。
