Firefox中的navbar品牌css问题

标签： html css twitter-bootstrap firefox

我最近意识到我的导航栏品牌形象在常用的网络浏览器Mozilla Firefox中无法正常显示。

css在Chrome和Internet Explorer（wat）中效果很好。

我已经尝试过使用css但我永远无法在Firefox中使用它。我检查过，似乎填充和Bootstrap在Firefox中无法正常工作存在问题。无论如何，这是我的代码：

我将我的代码放在CodePen中，因此它很容易获得，因为它是一个视觉问题：

你可以在Firefox中看到图像不像Chrome或IE那样显示。

感谢您的帮助。

答案 0 :(得分：3)

这是因为.navbar-brand的填充，如引导文档中所述

  

由于.navbar-brand有自己的填充和高度，您可能需要根据图像覆盖一些CSS。

此外，您的以下css声明似乎导致Firefox中的问题：

.navbar-brand img {
    margin-top: -7.7%;
    height: 160%;
}

将其替换为例如：

.navbar-brand img {
    height: 30px; 
    margin-top: -5px;
}

它应该跨浏览器工作。
