tell me more icon Meta Tag and Viewport Key

The meta tag places lines of code in between the <head></head> tags in your web page code. To improve the presentation of web page contents on mobile devices, use the viewport key on the meta tag to specify the initial scale and width of the viewport.

Insert HTML/JSP popup

You specify the contents of br-o.jspx to take up the entire viewport of the mobile device by setting the width to the width of the device, as shown in the following code:

<meta name="viewport" content="width=device-width;
      initial-scale=1.0; maximum-scale=1.0; user-scalable=0;"/>
