Certainly! A sticky header is a common feature on websites where the header remains at the top of the page as you scroll down. Here's a simple example of how you can create a sticky header using HTML, CSS, and JavaScript:

HTML:

CSS (styles.css):

css
body { margin: 0; padding: 0;}.sticky-header { background-color: #333; color: white; padding: 20px; position: fixed; top: 0; width: 100%; transition: top 0.3s;}.content { margin-top: 100px; /* Ensure content appears below the header */ padding: 20px;}

JavaScript (script.js):

javascript
const header = document.querySelector('.sticky-header');let prevScrollPos = window.pageYOffset;window.addEventListener('scroll', () => { const currentScrollPos = window.pageYOffset; if (prevScrollPos > currentScrollPos) { header.style.top = '0'; } else { header.style.top = '-100px'; // You can adjust this value to control the header's hiding distance } prevScrollPos = currentScrollPos;});

In this example, we have a basic HTML structure with a header element, content, and links to external CSS and JavaScript files. The CSS file (styles.css) defines the styling for the sticky header, while the JavaScript file (script.js) adds the functionality to make the header stick to the top of the page when the user scrolls down and hide it when they scroll up. Adjust the styles and values as needed to fit your website's design and requirements.
