Content on page is not centered

Hi Guys

Im finding my posts, even the header, especially with larger images are not centered and are far to the left.

I have customised the css to my liking but theres obviously something up.

The post on these pages show the problem, and also the header.

https://www.twentyfourhrs.net/?page_id=83

the css sheet is in the default folder which i assume is

twentyfourhrs.net/wp-content/themes/manifest_v1.1/style.css

any help would be greatly appreciated

thanks in advance
