SharePoint Customization

When I tried to build site using sandbox, I found many restrictions. The better solution for most of these problems do a workarounds using out of the box controls and Web parts of the SharePoint.

I found site give us good solutions for building some modules with small customization of out of the box SharePoint Web parts and Controls with css and javascript functions:
