Marshmallow theme maybe .... maybe so?

Ive started having ago at this today by altering my style to make it as easy to use (as I can anyway) as Kubrick. Seems to be going OK so far but Im concentrating on getting everything working and Ill play the the colours later. Also, because of my minimal CSS etc skills, Im sure some bit could be done better and Ive found a few issues with this site through having to check the code more carefully. The different php file 'modules' work slightly differently to the Kubrick for 1.3; for instance, whilst some divs open in one file and close in another on Kubrick, mine are all self contained. This makes it a bit easier to edit but also less flexible, its also down to the way my mind works (or doesnt) - as I cannot keep track of all the different divs in different files in my head. I wont put up any pics as Im still playing with it and its basically _this_ but paired down to minimal images and a different colour. I still have the stripes along the back, at the top but Ive done them as a gif in the body css tag but I wonder if that can be done as pure css? Oh yeah, and another thing .. the shadow either side of the middle bit ( ;-) ) is a png so that the stripes show through. Now, as IE (_spit_) doesnt show pngs properly should I do it some other way (ie drop the shadow)? *Edit:* _Note_, the screen grab on this post is from _this_ theme, *not* the one im making (working name *Mallow* - but itll probably stay). Visually its similar, but just alot less fussy and with just the one image file (If i remember correctly ... err, make that 3).
