Blog Pages text content produces gap to right

Hello,

On my blog pages, I've done some changes to the CSS to make it look the way it is now. However the text seems to be to be pushed to the left and cuts off a little at the right making a gap appear. How would I reduce the size of the gap to the right, if you need 'Support Access' let me know as I've made several major CSS changes to the structure of the page.
