I use content/sidebar layout. In most cases my sidebars take a 300×250 ad. I want to see if I can put two 160×600 ads side by side (next to each other). Not sure if that is possible or how to do that. I realize that comes to 320 wide so probably need to adjust the sidebar width, assuming that is can be done at all.
you would need to add both of the Ads to a single HTML Widget, increase the width of the Sidebar then we can take a look at some CSS to place them aside each other.
Well I tried that and it looks awful, as I expected it would. But since my site is live I did not want to leave it up like that. So I will keep checking around to see what can be done.
