We're happy to announce the release of the final element of Darwin's "Fluid" stage, Fluid Editor Preview. This tool allows a contributor to see what the published page will look like at the minimum and maximum fluid sizes, as well as his or her own screen size.The option is available in the upper left corner of the preview modal, on any community with Fluid Layout enabled. Check it out on the Community Test Wikia. As noted in the Darwin Webinar and on the Forum, we're currently working on bug fixing and evaluating user feedback about Fluid Layout and Special:CSS. So let us know what you think of all aspects of the "Fluid" stage!
We're looking ahead to determine when Fluid Layout and its related features will get a wider release, and we'll also be announcing more about how Wikia's evolution will continue, very soon.
