Im not a pro at this by any means. I tried following a few youtubes on this and was able to get the columns to work fine with paragraph tags. Though when I go with a ul > li tag. The image wants to take the whole space.
Im not really sure what the cause is here. Whats most perplexing is that it looks like the li / image has a right margin of the whole space. Even when I set it to zero.
When I inspect the element - that margin says 0 0 0 0 but mousing over I see it takes the whole page...
Code below ...

li are block level elements and they should take the whole right space, unless you make it inline by display: inline; in css property. then if you want the li to float to right or left you could do float: right/left; all in the li css property
