The CSS Form Builder tool is designed to help you craft advanced css designed forms including validation for the forms. The tool will generate a bit of css to accomplish this. Is there something specific that you are trying to do with the tool that you do not know how to do or an interface that you do not understand? If we are missing anything in the documentation or it is difficult to understand please be specific about what parts you are having trouble with or missing so that we can look into that.
