Hey Gabriel,
the blog page of your website looks like this in my Chrome browser – and it seems to be displaying all elements as intended. If this is not the case on your machine, please send me a screenshot or tell me which browser (and its version) you are using. Thanks!
Regarding the background image cropping – the current mechanism is the most efficient known rule, based on the CSS “background-size: cover” declaration. Since there are so many different possible screen sizes, any non-automated rules work less efficiently, according to experience; moreover, the background image will be cropped differently on various screen dimensions, i.e. the way it looks on your machine is not necessarily the way it will look for other users. You could try cropping the bottom half of the image before uploading it as a background image as well.
Sincerely,
Andrew / Satori Studio
