I m 学习《框架一》中的内容。
<span class="ui-icon ui-icon-circle-minus"></span>
produces an icon of a minus sign inside a circle.
Using the ThemeRoller Firefox Bookmarklet, I was able to change the color of the icon to red (to make it look like a delete button).
问题:我怎么能做一个红树,另一个颜色?
<span class="ui-icon ui-icon-circle-plus"></span>
我这样说是绿色的。
