Question

我的css如下：

   li {
-webkit-perspective: 400px;
perspective: 400px;
}

.info {
-webkit-transform: rotate3d(1, 0, 0, 90deg);
transform: rotate3d(1, 0, 0, 90deg);
width: 100%;
height: 100%;
padding: 50px;
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
border-radius: 4px;
pointer-events: none;
background-color: rgba(26, 188, 156, 0.9);
}

.in-top .info {
-webkit-transform-origin: 50% 0%;
        transform-origin: 50% 0%;
-webkit-animation: in-top 300ms ease 0ms 1 forwards;
        animation: in-top 300ms ease 0ms 1 forwards;
}

.out-top .info {
-webkit-transform-origin: 50% 0%;
        transform-origin: 50% 0%;
-webkit-animation: out-top 300ms ease 0ms 1 forwards;
        animation: out-top 300ms ease 0ms 1 forwards;
}
@-webkit-keyframes in-top {
from {
-webkit-transform: rotate3d(-1, 0, 0, 90deg);
        transform: rotate3d(-1, 0, 0, 90deg);
}
to {
-webkit-transform: rotate3d(0, 0, 0, 0deg);
        transform: rotate3d(0, 0, 0, 0deg);
}
}

@keyframes in-top {
from {
-webkit-transform: rotate3d(-1, 0, 0, 90deg);
        transform: rotate3d(-1, 0, 0, 90deg);
}
to {
-webkit-transform: rotate3d(0, 0, 0, 0deg);
        transform: rotate3d(0, 0, 0, 0deg);
}
} 
@-webkit-keyframes out-top {
from {
-webkit-transform: rotate3d(0, 0, 0, 0deg);
        transform: rotate3d(0, 0, 0, 0deg);
}
to {
-webkit-transform: rotate3d(-1, 0, 0, 104deg);
        transform: rotate3d(-1, 0, 0, 104deg);
}
}
@keyframes out-top {
from {
-webkit-transform: rotate3d(0, 0, 0, 0deg);
        transform: rotate3d(0, 0, 0, 0deg);
}
to {
-webkit-transform: rotate3d(-1, 0, 0, 104deg);
        transform: rotate3d(-1, 0, 0, 104deg);
}
}

人们说我需要添加！重要标签，但不知道在哪里

这是html

我希望我也提供js

var nodes  = document.querySelectorAll('li'),
    _nodes = [].slice.call(nodes, 0);

var getDirection = function (ev, obj) {
var w = obj.offsetWidth,
    h = obj.offsetHeight,
    x = (ev.pageX - obj.offsetLeft - (w / 2) * (w > h ? (h / w) : 1)),
    y = (ev.pageY - obj.offsetTop - (h / 2) * (h > w ? (w / h) : 1)),
    d = Math.round( Math.atan2(y, x) / 1.57079633 + 5 ) % 4;

return d;
};

var addClass = function ( ev, obj, state ) {
var direction = getDirection( ev, obj ),
    class_suffix = "";

obj.className = "";

switch ( direction ) {
    case 0 : class_suffix = '-top';    break;
    case 1 : class_suffix = '-right';  break;
    case 2 : class_suffix = '-bottom'; break;
    case 3 : class_suffix = '-left';   break;
}

obj.classList.add( state + class_suffix );
};

_nodes.forEach(function (el) {
el.addEventListener('mouseover', function (ev) {
    addClass( ev, this, 'in' );
}, false);

el.addEventListener('mouseout', function (ev) {
    addClass( ev, this, 'out' );
}, false);
});

Javascript和我的bootstrap cdn一起工作正常但我的css文件似乎被默认的bootstrap cdn覆盖了，需要帮助将！important标签添加到我的css文件中。

我几乎尝试了所有可能的事件但没有帮助

如果你可以帮助我，那将是非常有帮助的

请guyz需要认真帮助!!!

Answer 1

在Bootstrap CSS之后加载您的自定义CSS，您加载的项目顺序很重要。在您当前的顺序中，您的CSS加载然后Bootstrap会加载您的样式。

要修复，只需在Bootstrap加载后放置自定义CSS即可。

样式表无法使用bootstrap 4 CDN链接？
