Why is the library's web site using fixed-width columns in its CSS? We need to be able to see the right-hand side, not have to scroll to the right every time we want something. This is a major inconvenience to the majority of uchicago users, since most people are not working on large screens.
The Suggestions Office took this to our colleagues who run the Library's web programs, performing various feats of magic behind the scenes. Alas, their wizardry has limits: fixed-width CSS is a known problem of Lens and unlikely to disappear anytime soon.
Lens is a custom UChicago version of Aquabrowser Library (hence those "Powered by Aquabrowser" labels you occasionally see when surfing around in Lens), a product in use at many other libraries.
While we have some ability to customize Aquabrowser, the fixed-width CSS is embedded too deeply into the product -- changing it has to be done by the Aquabrowser developers.
In the meantime, we found 2 workarounds: (1) increase your screen resolution or (2) use the text-only version (http://lens.lib.uchicago.edu/accessible.ashx) -- this would still require some scrolling but doesn't rely as much on fixed-width CSS.
