Have you opened your website on a phone and noticed that the text is too small, images are cut off, or the page needs horizontal scrolling? These are common signs that your website is not mobile responsive. A responsive website automatically adjusts to different screen sizes, including phones, tablets, and desktops. Quick Tip: If your website looks fine on a computer but breaks on a phone, check its mobile layout and CSS first. Why Is My Website Not Responsive on Mobile? Here are some common reasons: 1. Missing Viewport Tag The viewport tag helps your website fit the phone screen. Add this inside the <head> section: <meta name=”viewport” content=”width=device-width, initial-scale=1″> 2. Fixed Widths Using large fixed widths can make your website wider than the phone screen. Use flexible widths instead:.container {     width: 100%;     max-width: 1200px; } 3. No Mobile CSS Your website may need media queries to change the layout on smaller screens. @media (max-width: 768px) {    .content {         width: 100%;     } } 4. Large Images Large images can overflow the screen. Use: img {     max-width: 100%;     height: auto; } 5. Small Buttons Buttons and links should be easy to tap on a phone. Give them enough size and space. Simple Check: Open your website on your phone. Check the menu, text, images, buttons, and forms. Make sure nothing is cut off or difficult to use.
