Designing and coding a sponsors page is part of the developer’s life (at least the lucky developer’s life, if it is about a personal site of theirs). It, however, follows different rules than those for the other pages of the site. You have to find a way to fit a lot of information and organize it clearly, so that the emphasis is put on your sponsors, and not on other elements of your design.
We are using PHP, CSS and jQuery with the jQuery Flip plug-in, to do just that. The resulting code can be used to showcase your sponsors, clients or portfolio projects as well.
