What makes your website responsive?

CSS (Cascading Style Sheets) code is primarily responsible for making a website responsive. Responsive design uses CSS media queries to apply different styles based on the user's screen size, orientation, resolution, and other characteristics. This allows the website layout and elements to adapt and display optimally across various devices, from desktops to mobile phones. Javascript can be used for dynamic content and interactive elements, but it's not the core technology for responsive layouts. Google Tag Manager is a tool for managing website tags (like analytics or marketing tags) and does not directly contribute to responsive design. A website is not automatically responsive; it requires deliberate design and coding using CSS to achieve responsiveness.
