下拉菜单具有奇怪的浏览器/操作系统兼容性问题。具体来说，我正在尝试设置选择元素的高度以匹配其旁边的文本输入。
在PC上，它可以在所有浏览器中正常显示。
在Mac上，在Firefox中可以使用高度，但是选择中的文本似乎过大（请参见下面的第一张图片）。
在装有Chrome的Mac上，高度设置不正确（请参见下面的第二个图像）。
这是相关的CSS：
form select {
float: left;
height: 40px;
font-size: 22px;
padding-top: 4px;
}
任何想法为什么我会遇到这种情况？有没有办法在浏览器和操作系统之间重置或标准化下拉菜单的样式？

Normalize.css与AlienWebguy的答案类似，但是使用一组更合理的默认值。他们的表单代码为：

/*

*/
form {
margin: 0;
}
/*

*/
fieldset {
margin: 0 2px;
padding: 0.35em 0.625em 0.75em;
}
/*
