Trouble with html displaying under the title bar

Tell us what’s happening:
Thanks in advance for your comments…

When the page initiates, everything looks fine…however, whenever I navigate (for example, clicking the link in the menu) The page is hidden by the menu bar at the top.

Your CSS code so far

html body {
  font-family: 'Open Sans', sans-serif;
  text-align: left;
}

.navbar {
  background-color: #333;
  overflow: hidden;
  position: fixed;
  text-align: center;
  top: 0;
  width: 100%;
  z-index: 500;
}

/* The navigation bar */
.navbar a {
  color: white;
  display: inline-block;
  padding: 15px;
}

/* Change menu item on mouse-over */
.navbar a:hover {
  color: red;
  background-color: darkgray;
  transition-duration: 0.5s;
}

/* Main content */
.main {
  margin-top: 55px;
}

h1 {
  background-color: aqua;
  border: 3px solid black;
  margin-bottom: 10px;
  margin-top: 10px;
  text-align: center;
}

.projects {
  display: grid;
  grid-template-columns: repeat(3, minmax(300px, 1fr));
}

.project-tile {
  border: 1px solid black;
}

#welcome-section {
  display: block;
  height: 100vh;
  margin-top: 0;
  padding-top: 0;
}
@media screen and (max-width: 600px) {
  .column {
    width: 40%;
    padding-top: 0;
  }
}

Challenge: Build a Personal Portfolio Webpage

Link to the challenge:

This is a frustrating issue to deal with, but a little magical css modifying should help with it. Regarding why it’s happening, if you click on the in-page link in your navigation bar, it will put whatever it is linked to at the very top of the page. Because the title is getting pushed to the top, it will go behind the absolutely positioned navbar.

This here is a helpful thread on the issue that might help you with your problem. Good luck!

Thanks for the help!
