Figure 6-8. The web page on the BlackBerry 10 device
There are two small buttons at the top-left and top-right corners of the browser window with arrows on
them. Use these to show/hide the option windows. For example, the one on the left, shown in Figure 6-9 , allows
you to change the device orientation or to choose a different platform to emulate. It also provides some technical
details of the current device such as the screen resolution. The button on the right includes the Settings tab where
you can switch between dark and light themes.
