css - UCO(未识别的 CSS 对象)在 Firefox 中向我的文本区域添加更大的字体大小

Question

我正在构建一个包含 3 个字段的表单:#name、#mail 和 #message。第一个和第二个字段的字体大小相同，但最后一个字段 (#message) 的字体大小仅在 Firefox 上更大。

这是我用 Firebug 检查时 #message 的 CSS:

 ....loading....

body {
color:#666666;
font-family:"Helvetica Neue",Helvetica,Arial,sans-serif;
font-size:14px;
line-height:130%;
margin:0;
padding:0;
}
screen.css (line 3)
#message {
height:100px;
width:200px;
}
global.css (line 189)
#name, #email, #message {
font-family:Arial,"MS Trebuchet",sans-serif;
margin:0 0 10px;
padding:6px;
}
global.css (line 182)

我的 Firefox chrome 文件夹 (userContent.css) 中有这个:

}

pre, code {

这是我用 Firebug 检查时 #name 的 CSS:

Answer 1

您可以对字体大小定义做的最好的事情之一是使用 em 单位大小而不是 px 大小。

不过，由于缺少其他两种样式(#name、#mail)，此 CSS 不能提供太多信息。对于其他两个，您可以轻松地比较它们，看看有什么不同。
