问题是:如果父母激活了我在这里得到的悬停事件,我想做一个应该悬停在子菜单上的“manuthing”:
HTML:
<div id="menuitem">Info</div>
<div id="menuitem">Foto</div>
<div id="menuitem">Sicherheit im Web</div>
<div id="menuitem">Projekte
<div id="submenuitem">SchülerInnenparlament
<div id="subsubmenuitem">
<a href="./subsubitem1.html">Aktuelles</a>
</div>
<div id="subsubmenuitem">
<a href="./subsubitem2.html">Text should be written here</a>
</div>
<div id="subsubmenuitem">
<a href="./subsubitem3.html">Text should be written here1</a>
</div>
</div>
</div>
<div id="menuitem" title="E-Learning">E-Learning</div>
<div id="menuitem" title="Kontakt">Kontakt</div>
CSS:
#subsubmenuitem
{
opacity:0;
-webkit-transition:.5s;
-moz-transition:.5s;
-o-transition:.5s;
-ms-transition:.5s;
transition:.5s;
}
#submenuitem {
opacity:0;
-webkit-transition:.5s;
-moz-transition:.5s;
-o-transition:.5s;
-ms-transition:.5s;
transition:.5s;
}
#menuitem:hover #submenuitem {
opacity:1;
}
#submenuitem:hover #subsubmenuitem {
opacity:1;
}
但div的内容是使用menuitem下的空格。它应该将其他div移动 - 而不仅仅是让事物变得不可见。 有人知道这个解决方案吗?
编辑:
ul
li
li
/ul
会更好吗?..

如果您在谈论显示/隐藏子菜单,请使用:
display: none
display: block
在此jsFiddle演示中查看结果。
#subsubmenuitem,
#submenuitem
{
display: none;
opacity:0;
-webkit-transition:.5s;
-moz-transition:.5s;
-o-transition:.5s;
-ms-transition:.5s;
transition:.5s;
}
#menuitem:hover #submenuitem,
#submenuitem:hover #subsubmenuitem
{
display: block;
opacity:1;
}
或者由于显示无法转换,请尝试使用此jsFiddle演示中的height
和overflow
。
#submenuitem,
#subsubmenuitem
{
-webkit-transition:.5s;
-moz-transition:.5s;
-o-transition:.5s;
-ms-transition:.5s;
transition:.5s;
opacity: 0;
height: 0;
overflow: hidden;
}
#menuitem:hover #submenuitem,
#submenuitem:hover #subsubmenuitem
{
opacity: 1;
height: auto;
}
