Question

我是新手，所以如果这没有意义，请原谅我。在这个CSS样式表的＃topbar2部分中，我希望显示图像NAFF_webtracker_logo.gif。我相信我需要覆盖文档的这一部分，因为这是从defaultstyle.css开始的。这是在我无法编辑defaultstylesheet.css的应用程序中。有没有办法可以覆盖此部分以显示我的徽标？我的编码似乎是正确的，但图像不显示。

感谢任何帮助。

Answer 1

您可以在CSS中使用！important关键字。这将覆盖默认样式。

#topbar2
{
    color: #ffffff;
    background: url(images/NAFF_webtracker_logo.gif) no-repeat top left !important; 
    height: 204px;
}
