Following the advice below, I added a quick inline div to experiment and see what it looked like. test page
After two hours of searching, reading and experimenting, I am still no closer to understanding why the home and email button are below eachother, and the other two next to each other.
I could understand if they were all juxtaposed or all superposed, but only the first and the last vertically?
Ralph, indeed the 4 at the top "home, gas, water, email".
