Need to make a 2 section box for content

I know little to nothing about css but I am trying.
I have a landing page that used to be filled up with a static image.

Now I need to change it to a css design with a revolving image, and a video I was told not to use tables.

The box that I need has two sections side by side in the center of the page, the first section is for a reotating image and is 450pixels the second is for a video player and is 255px
the height on both is 270px  there should be a 10px border between them but the remaining space on either side should be filled with grey and the content should always be centered.

sounds easy but nothing I do makes it even close.

Can someone code that for me?  Show me how to create the two boxes?
