Challenges, and other approaches
Although many publishers have implemented responsive designs, one challenge for responsive design adoption was that some banner advertisements and videos were not fluid. However, search advertising and (banner) display advertising came to support specific device platform targeting and different advertisement size formats for desktop, smartphone, and basic mobile devices. Different landing pageURLs have been used for different platforms, or Ajax has been used to display different advertisement variants on a page. CSS tables permitted hybrid fixed and fluid layouts.
