My forum top block overlaps

[spd2612]

Ok I guess I did this by accident. I am by no means a PHP coder
I forgot to take some extra code out when I created my garage block widget
I removed that code and re done the HTML and I got what I think is the correct screen all was lined up like it should with a white back ground even in IE, Chrome and Firefox. See the first screenshot ( Named Without ) I had made my header (at top transparent ) and liked that and had that look all the way thru the forum ( look at the forum now or see logged in screen shot ( WithLI) I was getting that affect because I had accidentally left <li at the end of the code I put in my forum block for a widget I made I have no idea why though lol
Is there a better way to get the look I have now with transparency all the way thru the forum home page I know what I am doing cant be right and I assure you was accidental ?

And thanks for guiding me in the right direction

I do have the code <li in the form block now below my widget code
