HTML won't validate!

I’ve got an error in my code, it won’t validate, I think it is because I have a div inside of an anchor, not sure though.

here is the error:
Line 141, Column 36: document type does not allow element “div” here; missing one of “object”, “applet”, “map”, “iframe”, “button”, “ins”, “del” start-tag

                	<div id="box4">

The mentioned element is not allowed to appear in the context in which you’ve placed it; the other mentioned elements are the only ones that are both allowed there and can contain the element mentioned. This might mean that you need a containing element, or possibly that you’ve forgotten to close a previous element.

One possible cause for this message is that you have attempted to put a block-level element (such as “<p>” or “<table>”) inside an inline element (such as “<a>”, “<span>”, or “<font>”).

here is my code:
<a href=“fitnesscoaching.html#dest_packages”>
<div id=“box4”>
<p>Physical Activity Counselling and Evaluation, Physical Goal Planner<br/><span>+</span> more</p>

You can’t use a block element (a div) inside of an inline element (an a).

Use span instead of div.

You have correctly identified the reason.

An <a> is an inline tag and therefore can’t contain block tags such as <div>

cool, thanks guys!

I’ve changed the div to a span, but now it will not validate because I have a p tag inside an anchor tag,
how can i correct this?

Change the p tag to a span as well and adjust your CSS code accordingly
