Responsive navigation header, the navbar This is an HTML, CSS, and JavaScript code for a responsive navbar. The navbar is fixed at the top of the screen and includes a burger menu icon on the left, a title in the center, and menu items on the right.
The CSS code includes media queries for adjusting the navbar layout for screens larger than 600px. The JavaScript code toggles a class on the body element to open and close the menu when the burger menu icon or the navbar-overlay is clicked.
The HTML code uses Google Fonts for the font family and Material Icons for the burger menu icon. It also includes a link to an external CSS file and a script tag for the JavaScript code.
