我在下面的代码中遇到了这个问题，我制作了这段代码，其中“div”在悬停时从右向左扩展，当鼠标离开底部区域（48x48px）时，我需要该扩展回来......</p> 

height: 800px;
    margin: 20px auto 20px auto;
    border: 1px solid #ebebeb;
    box-shadow: 2px 2px 4px #ebebeb;
    position: relative;
}


/* --- Shere buttons --- */

.share {
    position: absolute;
    top: 270px;
    right: 970px;
    width:161px;

您的代码段开头有一些不完整的 CSS 代码，我将省略。

如果我的问题是正确的，问题是当您将鼠标移动到左侧突出显示的区域时，带有 FB、TW 等的灰色区域没有突出显示。那是因为您不再将这个 div 悬停在右侧。

您需要添加一个选择器，以便当您将鼠标悬停在左侧 div 上时，右侧也应突出显示。因此，例如，您需要将选择器更改.fb:hover为.fb:hover, .share-botton-fb:hover .fb.

我还修复了 CSS 缩进并在 HTML 中添加了一个缺少的结束 div。

我不得不注释掉position: absolute;，.share因为那样你就不会在片段中看到 div 了。但是在您的网站上，您可能需要取消注释它。

这是代码：

/* --- Shere buttons --- */

.share {
    /*position: absolute;*/
    top: 270px;
    right: 970px;
    width:161px;
    height:auto;
}

.top-share{
    width: 145px;
    border-left: solid 1px #ebebeb;
    border-top: solid 1px #ebebeb;
    border-bottom: solid 1px #ebebeb;
    margin: 0px;
    background: #f7f7f7;
    padding-left: 15px;
    color: #777;
    font-family: Arial, Helvetica, sans-serif;
    font-size: 12px;
    line-height: 46px;
}

.top-share span {
    background: url(img/share-img.png) no-repeat  #f7f7f7;
    display: inline-block;
    width: 20px;
    height: 20px;
    position: relative;
    left: 4px;
    vertical-align: middle;
