How to make it appear on hover on an element?

Answer 1

Answer 2

Since links have icons and are likely to be made with a pseudo element, I thought I'd come up with a solution with only one pseudo element . And in general, if you can use one, then why write two ..

the code

<nav>
  <ul>
    <li><a href="">link</a></li>
    <li><a href="">link</a></li>
    <li><a href="">link</a></li>
    <li><a href="">link</a></li>
    <li><a href="">link</a></li>
  </ul>
</nav>

nav {
  width: 200px;
  background: #92aef4;
}

ul {
  --color: white;
  --radius: 30px;
  --smoothing-radius: 29.4px;
  border-right: 10px solid var(--color);
  padding: 0 0 2em 1em;
  list-style-type: none;
}

a {
  position: relative;
  display: block;
  padding: 0.5em;
  border-radius: var(--radius) 0 0 var(--radius);
  text-decoration: none;
  color: #6704f2;
}

a::before {
  content: "❄ ";
  color: white;
}

a:hover::before {
  color: deeppink;
}

a:hover {
  background: var(--color);
}

a:hover::after {
  content: "";
  position: absolute;
  right: 0;
  top: 50%;
  transform: translateY(-50%);
  width: var(--radius);
  height: calc(100% + 2 * var(--radius));
}

li:not(:last-child):not(:first-child) a:hover::after {
  background: radial-gradient(at top left, transparent var(--smoothing-radius), var(--color) var(--radius)) no-repeat top right / var(--radius) var(--radius),
    radial-gradient(at bottom left, transparent var(--smoothing-radius), var(--color) var(--radius)) no-repeat bottom 0 right 0 / var(--radius) var(--radius);
}

li:first-child a:hover::after {
  background: radial-gradient(at bottom left, transparent var(--smoothing-radius), var(--color) var(--radius)) no-repeat bottom 0 right 0 / var(--radius) var(--radius);
}

li:last-child a:hover::after {
  background: radial-gradient(at top left, transparent var(--smoothing-radius), var(--color) var(--radius)) no-repeat top right / var(--radius) var(--radius);
}
body {
  padding: 50px;
  margin: 0;
  font-size: 20px;
  font-family: 'Neucha', cursive;
  background: #eee;
}
