anything that will be in a book will be online for free.
if you know about adding styles etc you'll pick it up pretty quick you just have class="whatever" on your <p> or <span> or <a> tags etc then in your css sheet you have
p { FONT-SIZE: 12px; FONT-FAMILY: Verdana, Arial, Helvetica, sans-serif }
or whatever else you want.
also have a look at other peoples, view source, look where their style sheet is then open it.
