我想使用幻灯片效果隐藏和显示文章元素。当我加载页面并单击主页时，如果文章在屏幕上可见，则我编写的 js 将其隐藏得很顺利，很好，没有问题。但是当我单击关于Us Link，它立即显示文章，没有幻灯片效果。
这是显示和隐藏代码 + html + 消失的 CSS：
HTML：
<nav>
<ul class="sf-menu sf-vertical">
<li><a href=# onclick=home()>Home</a></li>
<li><a href=#about onclick=about()>About Us</a></li>
<li><a href=#>Cuisines</a>
<ul>
<li><a href=#starters>Starters</a></li>
<li><a href=#>Main Dishes</a></li>
<li><a href=#>Desserts</a></li>
<li><a href=#>Mezes</a></li>
</ul>
</li>
<li><a href=#>Wine List</a></li>
<li><a href=#gallery>Gallery</a></li>
<li><a href=#contacts>Contacts</a></li>
</ul>
