This month, Doug Bell will be talking about a CSS feature newly-supported by browsers: The flexible box (flexbox). Flexboxes makes laying out rows or columns fast and easy. Simple things become much easier, and even complex layouts become simple and responsive for a variety of display devices like phones and tablets. If you haven't learned anything about CSS in the last few years, or if you know the pain of using CSS floats, come learn about flexbox!
Doug Bell has been developing websites since the time of table layouts and spacer GIFs (pronounced "jifs"). He's developed websites professionally for 10 years, and is the organizer of the #css support community on the Freenode IRC network.
