Reducing Space before Footer

I’m sorry but it is really beyond the scope of these forums to deal with general CSS issues. Try a dedicated CSS resource such as https://www.css-discuss.org/ instead. In the meantime, try using Firefox with the Firebug add-on for this kind of CSS work. Or use whatever developer tool is available in your web browser.

you must edit style.css, and change height property of #footer

#footer{
height: 340px;

Thanks for information….
still confused but will try & sort it out!
