Content rendering

Browser content views

The BlackBerry® Browser can display content in Column View or Page View. In BlackBerry® Device Software version 4.5 or earlier,
Column View is the default view. In BlackBerry Device Software version 4.6 or later, Page View is the default view.

Description
Column View
In Column View, content is rendered vertically in a column the width of the screen. Content that exceeds
the width of the column is wrapped.
Table rows that extend beyond the width of the screen are wrapped, with the excess table cells displayed
immediately below.
On devices in which framesets are supported, the frameset layout is ignored. Instead, the BlackBerry
Browser displays the content of each frame vertically in the order in which they are encountered.
Page View
Page View was introduced in BlackBerry Device Software version 4.2.1, for BlackBerrydevices with a
trackball. Page View renders pages on a 1024 x 768 pixel canvas, appropriate for displaying content
designed for desktop computers, and scales the content to fit the width of the screen. Users can scroll
to the area of interest and zoom in to view the content at a standard size. When zoomed, the content
exceeds the width of the screen; users must scroll horizontally to view all of the content.
Page View is designed to display desktop-focused content in the BlackBerry Browser window. Content
that is designed specifically for the BlackBerry Browser should not be displayed in Page View.
To control how the content displays on the device, the BlackBerry Browser supports the
HandheldFriendly and viewport <meta> tags. To ensure that the content that is designed for the
BlackBerry Browser is displayed correctly, you must add one of the following tags to the <head>
element of your HTML content:
<meta name="HandheldFriendly" content="true" >
<meta name="viewport" content="width=device-width" >
