How To Create a Sticky Navbar

To create a sticky navbar, you will need to use CSS and JavaScript.

Here is an example of how you can create a sticky navbar using CSS:

1. First, add a position: sticky rule to the navbar element in your CSS. This will make the navbar stick to the top of the page when the user scrolls down.

nav {
  position: sticky;
  top: 0;
}

2. Next, add a z-index rule to the navbar element to ensure that it appears above other elements on the page.

nav {
  position: sticky;
  top: 0;
  z-index: 1;
}

3. You can also add a background-color and other styles to the navbar to customize its appearance.

nav {
  position: sticky;
  top: 0;
  z-index: 1;
  background-color: #333;
}

To create a sticky navbar using JavaScript, you can use the window.onscroll event to add a class to the navbar element when the user scrolls down.

Here is an example of how you can do this:

window.onscroll = function() {
  const navbar = document.querySelector('nav');
  if (window.pageYOffset > 0) {
    navbar.classList.add('sticky');
  } else {
    navbar.classList.remove('sticky');
  }
};

Then, in your CSS, you can define the sticky class to add the position: sticky, top, and z-index rules to the navbar element:

.sticky {
  position: sticky;
  top: 0;
  z-index: 1;
}

This will make the navbar stick to the top of the page when the user scrolls down, and remove the sticky effect when the user scrolls back to the top of the page.
