Meta Tags

viewport

Learn how to use the viewport meta tag to improve your site.

Defines how a website is displayed on mobile devices, influencing its width, scale, and initial zoom level. It is essential for creating responsive designs that adapt to various screen sizes.

Code Examples

Recommendations

  • Ensure Readability on All Devices
    Setting the viewport width to device-width and initial scale to 1 ensures your site is readable on all devices.
  • Avoid Large Fixed Widths
    Using a large fixed width can lead to a poor user experience on small screens, as users may have to scroll horizontally to view content.
