Do you like Ruby? Then this is for you: The official Ruby gem for CSS framework YAML, maintained by +Michael Schulze.

Fantastic work, Michael.

Do you use Emmet (former Zen-Coding)? Then this Gist from +Jens Grochtdreis might be helpful for you. It provides several snippets for typical HTML constructs for building the markup for YAMLs column and grid modules.

Yesterday, my browser-based rapid prototyping tool +Thinkin' Tags got a big update. The new version v0.5 comes with a fully redesigned user interface that is also much more responsive and many other new features.

For example, you can now create, duplicate, rename and delete stylesheets and you can organize which stylesheets are included and in which order for each HTML prototype.

And especially for YAML-based project: When creating new stylesheets, you can choose from several templates such as all the CSS files in yaml/screen/. So, you can now easily create prototypes of a new layout with multiple color schemes or play with different design variations of your navigation styles.

It's definitely worth a look, I promise.

Today, +Thinkin' Tags got another feature update. It now comes with full YAML 4.1.2 support. You can now update existing projects to the latest YAML version and the form construction kit is now fully supported.

Yesterday, YAML.de has moved to all-inkl.com. The change is run completely smoothly. If you should notice problems anyway, please let me know.
