我正在尝试做一个可以通用的滑动门按钮,除了 Firefox 之外,一切都很好。按钮中的 span 元素在 FF 中总是低于 2px。
这是示例
尝试这个:
button::-moz-focus-inner {
border: 0;
padding: 0;
}
(请注意,冒号 ( : ) 是双倍的,是的。)
在这种情况下,额外的填充是由一个不起眼的 Firefox 错误引起的。
(我自己也遇到了这个错误,我通过谷歌搜索在这个博客上找到了解决方案。)
Well, I don't know why this happens, but there is some strangeness here. It affects Safari as well, and it's slightly different. If you add a negative margin to the button span, it will move half the distance in Firefox than it does in Safari. So, the solution seems to offset the background-image. Here is one way to hack it:
/*grey button hacks non-IE*/
button.grey span{
background-position: 0 -1px;
}
button.grey:hover span{
background-position: 0 -36px;
}
button.grey:active span{
background-position: 0 -71px;
}
/* IE workaround. The \9 makes non-IE ignore these styles*/
button.grey span{
background-position: 0 0px\9;
}
button.grey:hover span{
background-position: 0 -35px\9;
}
button.grey:active span{
background-position: 0 -70px\9;
}
