You can use the Silk user agent strings to detect a particular Fire device and target the user experience accordingly. For more information about the Silk user agent string, see Learn about user agent strings.
Keep in mind the following when developing web content for Silk and Fire devices:
-
The viewport is the portion of the browser dedicated to displaying the webpage. Viewport size and screen size for mobile devices are not necessarily identical. They differ because the browser uses up some screen real estate to show its chrome. You can use the viewport meta element to specify attributes of the viewport, including width and height.
-
With a mobile form factor, HTML forms can be challenging for users to complete. You can use HTML5 input types to make forms more responsive.
-
You can use media queries to style your site for a specific screen resolution.
