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.
