如何在頁面刷新之前保持鼠標懸停狀態？

Question

我很難讓它正常工作。 我只想讓.accordion-content停留在未懸停狀態。 我已經嘗試了幾種方法來解決這個問題，但現在我幾乎全無所獲。 這是我正在使用的代碼：

HTML

<ul class="accordion-thing">
<li>
    <a>How do I setup my Chem+Nect Drum?<span>Learn More</span></a>
    <ul class="accordion-content">
        <li><em>01</em></li>
    </ul>
</li>

CSS

.accordion-thing,
.accordion-thing ul,
.accordion-thing li,
.accordion-thing a,
.accordion-thing span {
    margin: 0;
    padding: 0;
    border: none;
    outline: none;
}

.accordion-thing li {
    list-style: none !important;
}

.accordion-thing li > a {
    display: block;
    position: relative;
    min-width: 910px;
    min-height: 46px;
    padding: 0 10px 0 40px;

.accordion-content li:last-child a { border: none; }

.accordion-content li > a span {
    color: #797979;

.accordion-thing > li:hover > a,
.accordion-thing > li:target > a {

.accordion-thing > li:hover > a span,
.accordion-thing > li:target > a span {
    color: #fdfdfd !important;
    text-shadow: 0px 1px 0px rgba(0,0,0, .35);
    background: #00334c;
}

.accordion-content li:hover a { background: #efefef; }

.accordion-thing li > .accordion-content {
    height: 0;
    overflow: hidden;

    -webkit-transition: all .2s ease-in-out;
    -moz-transition: all .2s ease-in-out;
    -o-transition: all .2s ease-in-out;
    -ms-transition: all 2s ease-in-out;
    transition: all .2s ease-in-out;
}

.accordion-thing li:hover > .accordion-content {
    height: 98px;
}

我可以添加一些Javascript以使其正常工作嗎？

Answer 1

如果要在第一次懸停后直到頁面刷新之前永久應用懸停樣式，則必須使用javascript：

var accordion = document.getElementsByClassName('accordion-thing')[0];
accordion.addEventListener('mouseenter', function () {
    this.classList.add('hovered');
});

然后在您的CSS中，您擁有.accordion-thing li:hover {}任何地方，都可以將其更改為.accordion-thing.hovered li {}

這是一個簡單的例子來說明這個概念。
