Formatting not working in CMS PHP/HTML Widget?

[DJamieson]

I'm having some trouble with creating Widgets.

I have code which reads:

<h1>Hello</h1>

and

<div style="float:left">Goodbye</div>

And both of them are being displayed without the heading/alignment being properly applied, whether I create static HTML or echo through PHP.

The strange thing is that the code is being "output" to the source properly, but for whatever reason isn't being registered.

Can someone tell me what Im doing wrong?

(Im aware this has probably been answered somewhere, but I have looked and can't find anything).

Thanks in advance,
DJamieson
