由于"display:inline",CSS Hover-Effect在Firefox中不起作用

我的网站导航问题.有一个用"display:inline;"定义的按钮,因为否则按钮不会相互呈现水平.

然后我有一个动画,一个悬停效果.它必须是"display:inline-block;",因为没有它,Firefox就不会播放动画.

问题是我已经定义了"display:inline;" 首先,所以Firefox只是忽略"display:inline-block;" 并且动画不播放.问题仅出在Firefox中,而不是Chrome中,甚至不出现在IE中.

所以这是HTML代码:

这是CSS:

#nav {
    float: right;
    width: auto;
    font-size: 25px;
    margin: 12px 10px 0px 0px;
}

#nav li {
    list-style-type: none;
    display: inline;
    margin-right: 20px;
    padding: 5px 10px 5px 10px;
}

#nav a {
    text-decoration: none;
    color: #3a96d3;
}

.sweep {
    display: inline-block;
    vertical-align: middle;
    -webkit-transform: translateZ(0);
    transform: translateZ(0);
    box-shadow: 0 0 1px rgba(0, 0, 0, 0);
    -webkit-backface-visibility: hidden;
    backface-visibility: hidden;
    -moz-osx-font-smoothing: grayscale;
    position: relative;
    -webkit-transition-property: color;
    transition-property: color;
    -webkit-transition-duration: 0.3s;
    transition-duration: 0.3s;
}

.sweep:before {
    content: "";
    position: absolute;
    z-index: -1;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    background-color: #3a96d3;
    -webkit-transform: scaleY(0);
    transform: scaleY(0);
    -webkit-transform-origin: 50% 100%;
    transform-origin: 50% 100%;
    -webkit-transition-property: transform;
    transition-property: transform;
    -webkit-transition-duration: 0.3s;
    transition-duration: 0.3s;
    -webkit-transition-timing-function: ease-out;
    transition-timing-function: ease-out;
}   

.sweep:hover, .hvr-sweep-to-top:focus, .hvr-sweep-to-top:active {
    color: white;
}

.sweep:hover:before, .hvr-sweep-to-top:focus:before, .hvr-sweep-to-top:active:before {
    -webkit-transform: scaleY(1);
    transform: scaleY(1);
}

谢谢你的回答!

如果你#nav li也设置为,它应该没有区别display: inline-block;
