How to remove the bottom border of my dropdown menu?-CodePudding

I've finally succeeded in making my first dropdown menu thanks to the people in my previous post. I only have one problem left before I move on to making the main content and footer, the bottom border still appears in my dropdown menu.

* {
  margin: 0;
  padding: 0;
  background-color: white;
}

body {
  font-family: Arial, Helvetica, sans-serif;
}

header {
  background-color: rgb(255, 255, 255);
  height: 600px;
}

.navbar {
  width: 85%;
  margin: auto;
  padding: 60px 0;
  display: flex;
  align-items: center;
  justify-content: space-between;
}

.logo {
  width: 160px;
  cursor: pointer;
  margin-right: auto;
}

.navbar .dropdown {
  display: none;
  box-shadow: 0px 0px 2px #000;
  border-radius: 5px;
  left: -30%;
}

.navbar ul li:hover .dropdown {
  display: block;
}

.navbar>ul>li {
  position: relative;
}

.navbar>ul>li>.dropdown {
  position: absolute;
  top: 1.4em;
}

.navbar .dropdown li {
  display: block;
  margin: 15px;
  text-align: center;
}

.navbar ul li {
  list-style: none;
  display: inline-block;
  margin: 0 20px;
  position: relative;
}

.navbar ul li a {
  text-decoration: none;
  color: black;
  border-bottom: 0px;
}

.navbar ul li a:hover {
  color: teal;
}

.navbar ul li::after {
  content: '';
  height: 3px;
  width: 0;
  background: teal;
  position: absolute;
  left: 0;
  bottom: 0px;
  transition: 0.5s;
}

.navbar ul li:hover::after {
  width: 100%;
}

button {
  list-style: none;
  border: none;
  background: teal;
  padding: 10px 20px;
  border-radius: 30px;
  color: white;
  font-size: 15px;
  transition: 0.4s;
}

I already tried adding bottom-border: 0px in .navbar ul li a but to no avail.

CodePudding user response：

The rule .navbar ul li::after selects all children, if you just want to select the first child then use .navbar > ul > li::after instead.
