<div> and <span> question

With most things the way you call CSS style is usually the same, whether class or id.
so for div

the general rule is to use id for things you will only use once per page (same thing multiple pages is fine) class is really for styles you might use several times throughout a page
like text for example, you are usually better using a class for text as you tend to use that same text styling more than once per page

an id in css styling is labelled using a #
so

#id_name {
some css styling
}

stuff in the div

and class simply uses a dot

.class_name {
some css styling
}

stuff in the div

for the h1 h2

you can create all h1 styles with this:

h1{
font: bold 120% Arial,sans-serif;
color: #000000;
}

the above style will work whenever you use
change the colour to the green you want and the font styling to whatever you want
and of course add more things in there, like margins/padding
if you wanted a 20px gap under each h1 heading you can do that. margins will be best for blank spacing around a heading

so do the same for h2 and change the styling to whatever you want h2 to have
if both your h1 and h2 are to be the same except italic, you could just make the h1 without itallic
and wherever you use the h1 you can wrap the text in

eg
header will be green AND italic
but if you want to use the itallic header more than once you are better of making a second header h2 with italic
