I am having some of the same issues you have fixed for Arte a Marte regarding resolution size for longlivethearts.org. In order for the ads to fit, it is important that the width of the site is enlarged. This change would need to be responsive in desktop, mobile and tablet views. I would also give new codes for the banners on Long Live the Arts. The logo of Long Live the Arts would need to be centred vertically in the header. In short, the job would imply making the same structure corrections you have been working on for Arte a Marte.
