In Oxbridge Notes, I upped the font-size in Chrome to "v. large" for filming a screencast. This, however, broke the whole website's look, in that some elements did not scale correctly using the browser accessibility tools.
The reason was because I had hard-coded pixel font-sizes for some elements instead of using EM/REM units.
Never use pixel values for font-sizes.
