html - li > 填充未填充父 li div

Question

我想向我的“a”元素添加填充，这将决定父 div 的高度。尽管如果我添加它，父 div 不受影响。我似乎根本无法弄明白。

这是一个汉堡导航栏菜单。因此，当我单击我的图标时，它应该会降低导航栏，并且应该与“a”标签通过填充提供的高度相同。

<div id="side-menu" class="side-nav" v-bind:class="{'side-menu-open': isOpen}">
    <ul class="side">
        <li class="side"><a href="#">Home</a></li>
        <li class="side"><a href="#">About</a></li>
        <li class="side"><a href="#">Projects</a></li>
        <li class="side"><a href="#">Contact</a></li>
    </ul>
</div>


li.side {
    display:inline-block;
    margin-right: -4px;
}

li.side a {
    padding: 3em 2em;
    border-bottom: 1px solid #333;
    display: block;
    color: #fff;
    text-decoration: none;
    transition: 0.3s ease;
}

li.side a:first-child {
    border-top: 1px solid #333;
}

li.side a:hover {
    background-color: #333;
    transition: 0.3s ease;
}

.side-nav {
    transition: 0.4s;
    background-color: #222;
    width: 100% !important;
    height:0;
    position: fixed;
    z-index: 1;
    top: 0;
    left: 0;
    overflow: hidden;
}

.open {
    transition: 1s;
}

.side-menu-open {
    height: 70px !important;
}

.open-slide {
    transition: 0.4s;
}

.open-slide:hover {
    cursor: pointer;
}

您需要在此处将高度从固定值更改为自动。

.side-menu-open {
    height: auto;
}

默认情况下，a 是一个内联元素。顶部和底部填充将不适用。您可以将显示类型更改为 inline-block。

li.side {
  display: inline-block;
  margin-right: -4px;
}

li.side a {
  padding: 3em 2em;
  border-bottom: 1px solid #333;
  color: #fff;
  text-decoration: none;
  transition: 0.3s ease;
  /* added */
  display: inline-block;
}

li.side a:first-child {
  border-top: 1px solid #333;
}

li.side a:hover {
  background-color: #333;
  transition: 0.3s ease;
}

.side-nav {
  transition: 0.4s;
  background-color: #222;
  width: 100% !important;
  /*height: 0;*/
  position: fixed;
  z-index: 1;
  top: 0;
  left: 0;
  overflow: hidden;
}

.open {
  transition: 1s;
}

.side-menu-open {
  height: auto !important;
}

.open-slide {
  transition: 0.4s;
}

.open-slide:hover {
  cursor: pointer;
}
