Sticky navbar creating white space-CodePudding

I am making a personal website and I am having issues with my sticky navbar. When the site loads the navbar is intended to go on top of section #home but it generates a white space for itself and it's supposed to take the background image of section #home/be on top of it and on top of every other section on the website (SEE PICTURE)

CodePudding user response：

You can solve this by using the float property and setting the width of the navbar to 100%.

.navbar {
  width: 100%; /* new line */
  float: right; /* new line */
  clear: both; /* new line */
  z-index: 100;
  font-family: 'Heebo', sans-serif;
  display: flex;
  position: sticky;
  top: 1vh;
  justify-content: space-between;
  align-items: center;
  border-radius: 20px;
  background-color: rgba(80, 80, 80, 0.5);
  backdrop-filter: saturate(180%) blur(20px);
  color: white;
  border-radius: 20px;
