I was wondering if someone could give me a link to a website that explains the differance and when and where to use these tags: <div> <span> and <p>.

Thanks.

will tell you what they are and how to use them.

The basic differences are;

A div is a block level formatting element, and gives a generic structure to a document but has no presentational meaning.

A span is an inline formatting element with no presentational meaning

A p is a paragraph element, a block element and a structural element that has a presentational meaning.

Block elements have an implied line feed above and below. Inline elements do not.

Actually, the link above to w3.org, in the part "7.5.4 Grouping elements: the DIV and SPAN elements" says:
Since HTML does not include elements that identify objects such as "client", "telephone number", "email address", etc., we use DIV and SPAN to achieve the desired structural and presentational effects.

So, yes, we can use DIV and SPAN for presentational meaning.
Greetings!

They can, provided they are styled as such, however they have no inherent meaning to non visual user agents.
But then of course the example given promptly uses a table, which has inherent structural meaning, for setting the data out.

Using a definition list would be a better way of structuring contact details
