Well, now that I play with it, maybe not exactly “fine” – LOL! When I implement it in Epik it seems to have some differences from the sample. For instance, it requires a manual toggle to turn it back on when a window is resized and it also seems to create a permanent toggle switch in the nav bar. The scheme at my original link seems much more elegant (see the example on the author’s own site). But in either example, I’m thinking there’s just some epik-specific tweak I’m missing? Appreciate the help!
