使用纯CSS向上/向上打开的下拉菜单

html

我使用纯CSS创建了一个下拉菜单,并且将其放到我喜欢的地方,但我希望它是“下拉”而不是“下拉”,因为菜单栏位于菜单的底部。布局。我需要添加或更改以使其成为“下拉菜单”吗?

#menu * {

  padding:0;

  margin: 0;

  font: 12px georgia;

  list-style-type:none;

}

#menu {

  margin-top: 100px;

  float: left;

  line-height: 10px;

  left: 200px;

}

#menu a {

  display: block;

  text-decoration: none;

  color: #3B5330;

}

#menu a:hover { background: #B0BD97;}

#menu ul li ul li a:hover {

  background: #ECF1E7;

  padding-left:9px;

  border-left: solid 1px #000;

}

#menu ul li ul li {

  width: 140px;

  border: none;

  color: #B0BD97;

  padding-top: 3px;

  padding-bottom:3px;

  padding-left: 3px;

  padding-right: 3px;

  background: #B0BD97;

}

#menu ul li ul li a {

  font: 11px arial;

  font-weight:normal;

  font-variant: small-caps;

  padding-top:3px;

  padding-bottom:3px;

}

#menu ul li {

  float: left;

  width: 146px;

  font-weight: bold;

  border-top: solid 1px #283923;

  border-bottom: solid 1px #283923;

  background: #979E71;

}

#menu ul li a {

  font-weight: bold;

  padding: 15px 10px;

}

#menu li {

  position:relative;

  float:left;

}

#menu ul li ul, #menu:hover ul li ul, #menu:hover ul li:hover ul li ul {

  display:none;

  list-style-type:none;

  width: 140px;

}

#menu:hover ul, #menu:hover ul li:hover ul, #menu:hover ul li:hover ul li:hover ul {

  display:block;

}

#menu:hover ul li:hover ul li:hover ul {

  position: absolute;

  margin-left: 145px;

  margin-top: -22px;

  font: 10px;

}

#menu:hover ul li:hover ul {

  position: absolute;

  margin-top: 1px;

  font: 10px;

}

添加bottom:100%到您的#menu:hover ul li:hover ul规则

#menu:hover ul li:hover ul {
    position: absolute;
    margin-top: 1px;
    font: 10px;
    bottom: 100%; /* added this attribute */
}

还是要防止子菜单具有相同的效果,只需添加此规则

演示2

#menu>ul>li:hover>ul { 
    bottom:100%;
}

为了获得边框,您可以添加以下属性

#menu>ul>li:hover>ul { 
    bottom:100%;
    border-bottom: 1px solid transparent
}
