Because current and future Opera for Android releases are based on Chromium, we can't use the current Opera desktop releases to connect to them (wait for Chromium-based Opera desktop releases for that).

    By Chris Mills · Wednesday, April 10, 2013 0

    The CSS Flexible box module level 3 brings with it a lot of power and some very exciting possibilities for web development, allowing us to put together complex site layouts easily and rapidly, and dispensing with some of the illogical hacks and kludges that we've traditionally used.

  • Native CSS feature detection via the @supports rule

    By Chris Mills · Wednesday, November 21, 2012 24

    We have practised feature detection to allow us to provide appropriate code to browsers with differing levels of standards support for a while now, but we've always needed 3rd party libraries to handle it.
