deploy* is an open source web application that enables you to create your web project framework with ease.

It lets you to choose the:

• XHTML document type
• CSS file (blank or with resets)
• jQuery to be included or not. If yes, ask for some popular plugins
• major directories like images, includes to be added

Once the link that creates to project framework is bookmarked, same framework can be created with just a click.

The idea itself is very nice: “instantly starting a project with the preferred structure“. If more libraries, CSS frameworks would be supported, it can become much more flexible (as it is open source, anyone can add these).

There are four buttons on this example, each of which has three states. That would normally be 12 images (thus 12 server requests), but thanks to the CSS sprites technique it is only one. The technique is demonstrated practically in the form of an accordion widget.

SenCSs is a CSS framework that doesn’t provide a layout system but aims to take care of the rest, like:

• fonts & font-sizes
• paddings
• margins
• colors,
• tables & lists
• headers, blockquotes and what more..

SenCSs has support for forms which helps presenting them nicely (better form support is on the way).

There are also styles for elements like errors, warnings or success messages which are parts of a standard web application.

SenCSs, although being fresh & currently in development, is a nice base to start with & improve depending on your needs.
