Does UIWebView in iOS 3 not support webkit column layout?

Question

I am using -webkit-column- ... css properties to accomplish nice line breaks in my UIWebView:

   #content {
    height: 460px;
    -webkit-column-width: 320px;
    -webkit-column-gap: 0px;
    }

This way text lines wraps from page to page without being cut off in the middle (book style).

It works perfectly from the iOS 4.x, but not in iOS 3.x (3.0, 3.1). Where can I find detailed UIWebView changelog of supported css attributes?

Answer 1

经过测试后，再次检查并使用iOS 4运行相同的样式-看来此CSS属性仅从4.x起得到支持。
