How do I get the links to work in my navigation bar?

So I've been tinkering with HTML and CSS for a little bit (please excuse my presentation) and I've been trying to get a fixed navbar working with inpage links that go the different sections within my one page website. I've knocked this up this morning and I can't for the life of me get the links to work.

I've had a google and there's a few similar posts saying that the z-index is the issue but I've had a play about with it and I still can't get them to work.

...anyone fancy shedding some light on it for me?

html {

}

body{
  font-family: 'Nunito';
  background: linear-gradient(#8FB0B7, #E8EFF0);
}

header {
  background-color: #e6763c;
  box-sizing: border-box;
  padding: 0 2rem;
  text-align: center;
  position: fixed;
  top: 0px;
  right: 0px;
  width: 100vw;
  display: flex;
  justify-content: space-between;
  align-items: center;
  z-index: 1;
}

ul {
  margin: 0;
  padding: 20px;
  list-style: none;
  /* border: 1px solid black; */

}

li {
  display: inline-block;
  padding: 10px;
  margin: 0 0 0 2.5em;
  background: #DDCFB199;
  text-align: center;
  border-radius: 5px;
  transition: all 0.2s ease;
}

.container {
  height: 100vh;
}
/* On hover animations */
li:hover{
  box-shadow: 0px 0px 7px 7px #3333;
  transform: scale(1.02);


}
/* Mobile */

@media (max-width: 900px) {
  header {
    background-color: #e6763c;
    box-sizing: border-box;
    padding-left: 0.2rem;
    right: 0px;
    text-align: center;
    position: fixed;
    width: 100%;
    display: flex;
    flex-direction: column;
    justify-content: space-around;
    align-items: center;
  }

  li {
    display: block;
    margin:   1.2rem;

  }
}

Solution

Your innerHTML is empty inside your <a> tags. This worked for me Put this for your links instead:

<li><a href="#new">New Memorials</a></li>
