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.
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;"/>
