Opera released special builds of Opera 12 by disabling WebGL and hardware acceleration with support for getUserMedia method enables users to video input from a user’s webcam and native pages code named Opera Reader build on top of CSS allows to split content into pages for better reading experiencing on touch screens such as tablets.
Opera reader using CSS turns continuous scrolling of single page content into multiple pages with “previous” and “Next” buttons at the bottom for navigation. With Opera Reader pages can be turned through gestures than with point and click and page scrolling is avoided here.
Opera says “You’ll be able to control the page browsing via swiping the page in different directions on touch screen devices, using the cursor keys on a device with a keyboard, and by activating the on-screen control buttons in any way you choose to do so”.
