<p class="description">It&rsquo;s been brought to my attention that OSX/Safari doesn&rsquo;t support :active for buttons with default settings, so you guys will have to resort to JS or hold down your mouse button to keep :focus triggered.</p>

并无法弄清楚如何将扩展按钮的高度调整为内容高度。目前弹出窗口的高度为：

.distribution-map .map-point:active, .distribution-map .map-point:focus{
     ...
     height: 220px;
     ...
}

我需要最小高度为100px，但当内容较大时，弹出窗口应相应增加。我无法通过设置min-height的{{1}}来实现此功能，因为内容始终居中并超出可见区域，因此无法正常工作。我很感激任何建议。

如何在纯Css Map中将div调整为内容高度？
