I have managed to figure out a few of the errors in my html (which I am in the process of fixing) but the following has stumped me:

Line 14, Column 88: document type does not allow element "h1" here; missing one of "object", "applet", "map", "iframe", "button", "ins", "del" start-tag.
…"></a> <span class="display-none"><h1>Imaginez Cannes - Creative Food and Par

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>").

I've tried tweaking bits but still can't get to the bottom of it... please help!!!
