Thanks for sharing, Ian! Yes, this snippet should do the job; I’m calling the likes of it “hacky” because it assumes we know the footer height in advance, which is usually not the case when developing themes that will potentially be used by thousands of people – who might put different amounts of content into the footer (in addition to that, on smaller screens that content will pack into a larger number of lines and therefore further change its height quite unpredictably, complicating this even further). However, for a specific website, where you do know the desired height of the footer, that can indeed be a neat solution.
Sincerely,
