Is there a website which tells you what other tags are allowed in a parent tag?

For instance, what tags are allowed inside <p></p>? Or What tags are allowed inside <a></a>? etc. etc.

Well, I don’t know of any site specifically telling that but there are general rules:

Block-level elements and table cells can contain other block-level elements and inline elements.
Inline elements can only contain other inline elements.
Paragraphs are a special case of block element: They can only contain inline elements, too.
Forms are block-level elements and can hold anything but input elements can’t be direct children, they must be in some other block-level container (e. g. a. fieldset).

Now you only need to find out what is a block-level element and what an inline element.

Try looking around w3schools.com. The previous post pretty much mentioned everything, but just validate everything time to time to see if theres anything you've missed.

..and there are some special tags like <ul>,<ol>,<li>,<dd>,<dt>,<dd> etc, for which we need to obey some nesting rules. Refer http://htmldog.com/reference/htmltags/ul/ and related links.
