Answer 1

The echo(); function you are using essentially prints HTML, this HTML can be styled by including a style sheet (Google CSS basics and you will quickly find out how to do this).
I would advise running this script and using the web inspector of your chosen browser to look at the HTML code you have created using your PHP code. Again, if your not familiar with the web inspector Google how to open it on your chosen browser.
Hope this clarifies things a bit :)
