Unwanted CSS!!! Please help!3

I created a custom header in photoshop/dreamweaver with slices and rollover images. You can see it here! Anyway, I created a block at the top of the page for my custom header and pasted the html into that block. The problem is that I'm getting padding from the "td" tag and line-height from "body" style in my default.css file. It's splitting up all of my slices. I've tried putting style attributes into the code within the block itself. I put style attributes into the style sheet and even tried hard wiring it directly into page.tpl.php. The wierd thing is that other style attributes work. For example, I can assign a background color and it reads it but I'll also say no padding and no line-height and it still renders whats on the style sheet.
