我有侧边栏菜单。 #menu li a有一个transform: scale(1.1) 我想在li内缩放文本和图标，并保持宽度相同 我试过overflow:hidden，但子菜单没有显示

任何帮助？

我在显示背景和文字/图标内容的a标签之间插入了一个容器。我使用了div，因为您的span已经如此风格化了。

我将容器添加到第一个和第二个，只是为了演示子列表仍然显示。

在样式中查找您的a:hover选择器已更改为a:hover .expandable。

div.expandable {
    display: inline-block;
}

.page-container {
    min-width: 1260px;
    position: relative;
    top: 0;
    left: 0;

    width: 100%;
    height: 100%;
    margin: 0px auto;
}

.content {
