CSS and PHP Developer Required

Hi I need someone to spend a few hours on making a few changes on my website: I have the following issues: - Footer needs adjusting - Classes and Elements need to be created for part of text - An image on the website only appears on Chrome and not on Firefox - Centralise text If you have good knowledge in PHP and CSS then you should not have any issues, The project should be completed within the next few hours, A good chance for someone to get a quick review, Thanks
