Today's web developers must create pages that display correctly on every device—smartphones, tablets, and desktop computers. That's where Opera Mobile Emulator comes in: a perfect mobile environment (browser) for testing your web pages right from your desktop computer.
What Is Opera Mobile Emulator?
Opera Mobile Emulator is an application created by Opera that uses the same engine and interface as the Opera Mobile browser (it shares the same code), so you can check whether your designs are fully responsive.
Once you download the application from its official page, you'll need to select the language and choose the mobile device, or customize the device (that's the type of screen).
Why Testing on Popular Devices Matters
But we want to stop at this point, because it's very important that your website can be viewed on most smartphones (preferably the best-selling ones). There's no point in it looking perfect on an LG Optimus 3D if the design breaks on an HTC Hero. The emulator also has a window where you can choose from several devices (HTC, LG, Motorola, Nokia, Samsung, and Sony, among other brands) and make your design more universal.
From this window you can also adjust the screen resolution, pixel density, user interface, user agent string, and window scale.
From its interface you can customize it to the fullest, use keyboard shortcuts, profile selector, and remote debugging, among other options.
Opera Mobile Emulator is truly a very good mobile browser emulator, and you can install it easily on your desktop (without needing to install the SDK). It's a free application available for Windows, Mac OS X, and Linux.
