How do I make the navbar stay within the parent div (hero image) regardless of screen size?

I adjusted it based on my screen size, and I’ve tried using both relative and absolute positions for .navbar, but when I open it on my laptop the navbar content overflows the parent image, setting overflow to hidden doesn’t fix the issue since i want it to stay over the bottom of the image at all times regardless of screen size. Here’s the jsfiddle https://jsfiddle.net/Montinyek/4dbf5p9e/1/


body, html {
  height: 100%;
  margin: 0;
  padding:0;
  font-family: Times, Times New Roman, serif;
}

.hero-image {
  background-image: linear-gradient(rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.2)), url(./hero.jpg);
  height: 80%;
  background-position: center;
  background-repeat: no-repeat;
  background-size: cover;
  position: relative;
  overflow: hidden;
}

.hero-text {
  text-align: center;
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  color: #f2f2f2;
}


h1 {
  padding: 80px 60px;
  border: 1px solid #f2f2f2;
  border-radius: 5px;
}

.nav-container {
  display: inline-block; 
  position: relative;
  top: 87%;
}

.navbar {
  overflow: hidden;
  height: 100px;
  display: inline-flex;
  gap: 70px; 
  align-items: center;
  justify-content: center;
  width: 99vw;
  
}

.navbar a.main {
  color: #f2f2f2;
  padding-left: 47px;
  padding-right: 47px;
  padding-top: 10px;

  transition: all 0.3s;
  display: block; 
}


.navbar a.main:hover  {

  transition: all 0.5s;
  
}

.dropdown-content a {
  float: none;
  color: #ddd;
  padding: 12px;
  text-decoration: none;
  display: block;
  text-align: center;
  transition: all 0.5s;
