Learn how to Create a Easy Sticky Header with CSS: Complete Educational in 2024




Want to make a sticky header with CSS?

No problem.

You simply add this CSS to your header HTML:

header {
  position: sticky;
  top: 0;
}  

In this article, we’ll dive in deeper to create a CSS sticky header from scratch. You’ll also learn how you can do it in WordPress.

Let’s dive in.

Create an HTML and CSS Sticky Header

Sticky headers will stick to the top of the browser when people scroll down the page. This is great for keeping your sticky navigation menu on display at all times, providing a better user experience.

Let’s look at the code.

HTML

This is a basic example of the HTML:

<header>
  <h1>My Website</h1>
  <nav>
    <ul>
      <li><a href="#">Home</a></li>
      <li><a href="#">About</a></li>
      <li><a href="#">Services</a></li>
      <li><a href="#">Contact</a></li>
    </ul>
  </nav>
</header>

The main container is a <header> and it has a simple <h1> for the logo and a <nav> for the navigation menu.

The important element is the <header> as this is what we’ll assign the CSS to to make it sticky. What goes inside this element is up to you; the fixed header will stay the same.

We’ll add more HTML and CSS later to add some style and to see the CSS sticky header scroll in action.

Sticky Header with CSS

CSS

Now let’s look at the CSS again:

header {
  position: -webkit-sticky; /* Safari */
  position: sticky;
  top: 0;
}

We can target the header section with header { } and add the CSS position element with the sticky property and top: 0 to make it stick to the top of the page.

We can also add position: -webkit-sticky for Safari browser support and older browsers.

Position: sticky works by combining position: relative and position: fixed together. That means the element will act like a relative element until the user starts scrolling. Then it stays fixed to the top or however many pixels you define with top: 0.

Here is some more code to add more style to the header. This will add text and background color, add some padding, and align the logo and navigation.

header {
  position: -webkit-sticky; /* Safari */
  position: sticky;
  top: 0;
  background-color: #000;
  color: #fff;
  padding: 25px;
  display: flex;
  justify-content: space-between;
  align-items: center;
}

Here’s the final header CSS together, which we’ll explain further in the post:

header {
  position: -webkit-sticky; /* Safari */
  position: sticky;
  top: 0;
  background-color: #000;
  color: #fff;
  padding: 25px;
  display: flex;
  justify-content: space-between;
  align-items: center;
  transition: padding 0.3s ease;
}
header.scrolled {
  padding: 5px 25px; /* Adjusted padding when scrolled */
}
header h1 {
  margin: 0;
  padding: 0;
  font-size: 24px;
  text-align: center;
}
nav ul {
  list-style: none;
  padding: 0;
  text-align: center;
}
nav ul li {
  display: inline;
  margin: 0 10px;
}
nav ul li a {
  color: #fff;
  text-decoration: none;
}
nav ul li a:hover {
  text-decoration: underline;
}

JS to change The Height on Scroll

Want to make the header reduce in size when you scroll?

No problem.

Here’s some JavaScript to make it work:

window.addEventListener('scroll', function() {
 // Select your header
 var header = document.querySelector('header');

 // Check if the scroll position is greater than 50 pixels
 if (window.scrollY > 50) {
  // Add a CSS class to reduce header size
  header.classList.add('scrolled');
 } else {
  // Remove the CSS class to restore header size
  header.classList.remove('scrolled');
 }
});

This will shrink the size of the header so that it doesn’t take up unnecessary space on the page yet keep the navigation in view.

Let’s break it down to see how it works:

  1. window.addEventListener('scroll', function() { ... }): This is an event listener that triggers when the window is scrolled.
  2. var header = document.querySelector('header'): This line selects the header element from the HTML document and assigns the header variable, allowing it to be targeted later in the code.
  3. if (window.scrollY > 50) { ... } else { ... }: This condition checks if the vertical scroll position is greater than 50 pixels. If it is, the code inside the first block is executed; otherwise, the code inside the else block is executed.

You’ll need to add this CSS as well, as it will define the size of the header once scrolled:

header.scrolled {
  padding: 5px 25px; /* Adjusted padding when scrolled */
}

To add an effect when the header gets smaller, add this piece of CSS to the header tag:

header {
  transition: padding 0.3s ease;
}

How to Make Any Header Sticky Using the Inspect Element

What if you already have a site with a header that isn’t sticky or fixed?

Whether it’s your own website or one you’re working on, you can make the header sticky using the inspect element tool.

Browsers like Chrome and Firefox have this built-in, so you can test out the code before saving it in the backend.

Just right-click in the browser and select Inspect Element:

Inspect element

Then click on the inspect icon:

Hover over and click the header to target the element:

Highlight HTML element

The element will show up in the style editor. Add the CSS code to make the header stick to the top of the page:

Now, your header will stay fixed when you scroll down the page. You’ll need to update this code in your main stylesheet to make it work for everyone.

WordPress themes like Astra, OceanWP, and GeneratePress have this option available. All you have to do is activate it in the theme customizer.
