为什么我的块的内容会在其他块上溢出？

Question

我在 Drupal 8 和 Bootstrap 上创建了一个页面，其中包含一个“了解更多”按钮来展开信息。

当信息被折叠时，块溢出。灰线和标签在上块溢出。

我该如何解决这个问题？谢谢

这里的灰线和标签溢出：

当信息展开时，它是好的：

CSS：

#readmorecollapse div.collapse[aria-expanded="false"] {
    height: 100px !important;
    overflow: hidden;
    visibility: visible;
    display: -webkit-box;
    -webkit-line-clamp: 2;
    -webkit-box-orient: vertical;  
}

#readmorecollapse div.collapsing[aria-expanded="false"] {
    height: 42px !important;
}

#readmorecollapse .readmorebutton a {
    width: 100%;
}

#readmorecollapse .readmorebutton .collapsed  {
    box-shadow: 0px -10px 25px 0px rgba(255, 255, 253, 0.8);
}

#readmorecollapse .readmorebutton a.collapsed:after  {
    content: 'Afficher toutes les infos';
}

#readmorecollapse .readmorebutton a:not(.collapsed):after {
    content: 'Cacher';
}

Answer 1

问题是您需要将overflow: hidden; 设置为div#collapserm 的第一个孩子。 css 代码必须是：

/* Here you need to remove the overflow */
#readmorecollapse div.collapse[aria-expanded="false"] {
    height: 100px !important;
    visibility: visible;
    display: -webkit-box;
    -webkit-line-clamp: 2;
    -webkit-box-orient: vertical;  
}

/* Then add a new rule for the first child */
#readmorecollapse div.collapse[aria-expanded="false"] div:nth-child(1) {
    overflow: hidden;
}

#readmorecollapse div.collapsing[aria-expanded="false"] {
    height: 42px !important;
}

#readmorecollapse .readmorebutton a {
    width: 100%;
}

#readmorecollapse .readmorebutton .collapsed  {
    box-shadow: 0px -10px 25px 0px rgba(255, 255, 253, 0.8);
}

#readmorecollapse .readmorebutton a.collapsed:after  {
    content: 'Afficher toutes les infos';
}

#readmorecollapse .readmorebutton a:not(.collapsed):after {
    content: 'Cacher';
}
