html - 如何定位下拉菜单

Question

我有一个带有选项卡的菜单，由于某种原因不想靠近菜单的左侧。我尝试删除所有其他填充内容等，但它并没有影响菜单边缘和选项卡文本之间奇怪的额外空间。

另外，我想让下拉菜单在 ul li ul li 标签周围没有填充，只有父标签本身。下图左边是当前元素 https://codepen.io/gracethelittleartist/pen/EvMbNR?editors=1100 ) 右边显示了我想要的样子。

ul{list-style:none;}
a{ text-decoration: none;color: black;}

.ul-li {position: relative;}

ul li {padding:10px;}

.ul-li > .ul-li-ul {max-height: 0;transform: scaleY(0);}

.ul-li > input[type="checkbox"] {
  opacity: 0;
  display: block;
  position: absolute;
  top: 0;
  width: 100%;
  height: 100%;
  cursor: pointer;
}
.ul-li > input[type="checkbox"]:checked ~ .ul-li-ul {
  max-height: 9999px;
  display: block;
  -moz-transform: scaleY(1);
  -ms-transform: scaleY(1);
  -webkit-transform: scaleY(1);
  transform: scaleY(1);
}


.ul-li {position: relative;}
.ul-li > .ul-li-ul {
  max-height: 0;
  overflow: hidden;
  list-style: none;
  padding: 0;
  margin: 0;
  transform: scaleY(0);
  transform-origin: 50% 0%;
  transition: transform 0s ease-out 0.6s,max-height 0.6s ease-out;
}

.ul-li > .ul-li-ul li a {
  display: block;
  background: #E3E3E3;
  padding: 10px 10px;
}
.ul-li > .ul-li-ul li a:hover {background: #D1D1D1;}

.ul-li > input[type="checkbox"] {
  opacity: 0;
  display: block;
  position: absolute;
  top: 0;
  width: 100%;
  height: 100%;
  cursor: pointer;
}
.ul-li > input[type="checkbox"]:checked ~ .ul-li-ul {
  max-height: 900px;
  display: block;
  transform: scaleY(1);
  animation: showAnimation 0.5s ease-in-out;
  transition: max-height 2s ease-in-out;
}
.ul-li > input[type="checkbox"]:checked + a[data-toggle="dropdown"]:before {
  transition: transform 0.6s;
}

nav ul li:not(.search):hover {background: white;}

@keyframes hideAnimation {
  0% {transform: scaleY(0.5);}
  60% {transform: scaleY(0.25);}
  80% {transform: scaleY(0);}
  100% {transform: scaleY(0);}
}

    .wrap {
  position: relative;
  z-index: 1;
  background: #E8E8E8;
  max-width: 330px;
  margin: 0 auto;
    }

你的问题是这样的:

ul li {padding:10px;}

如果您仅为父级指定此项，则一切正常。提示:使用 Google Chrome 的检查功能来(取消)激活 CSS 样式。
