This week in CSS we have some good 'flexbox' links for you to get your teeth into among other things.
If you haven't heard of flexbox then now's the time to get started as support is growing and in a couple of years will be a major layout tool in CSS. Unfortunately its not the easiest of modules to understand so it really is a matter of practice and trial and error so that you are ready to deploy when the time is right.
