Online CSS Layouts designer

I'm always on the lookout for great tools that aid in the design of my page layouts. Today I came across a site that lets you design your layout online! Its called YAML (Yet Another Multicolumn Layout).

The site describes it as: YAML is an (X)HTML/CSS framework for creating modern and flexible floated layouts. The structure is extremely versatile in its programming and absolutely accessible for end users.

• Based on web standards
• Accessible
• Flexible
• Easy to use
• Fully documented

This system allows for the rapid development of designs with one to three columns, with fixed or variable widths. With subtemplates (flexible grids), the column system can be endlessly nested and expanded. The YAML basis layout can be extended with special containers which help set the layout width or can create a border around the layout. YAML is more than just a simple multicolumn layout. It is an entire layout framework, highly flexible, and tested under real-world conditions with Cross-Browsers Compatibility.

The YAML Builder comes as a beta version v1.0 is now available that allows the visual development of YAML based CSS layouts directly within your web browser.
