Use Small caps please
Even though it’s officially known that ALL-CAPS ROT THE BRAIN, some people still use them.
Dear writers, please reconsider. And if you must, Please use small caps. They are lighter on the eye, and properly distinguish between UPPERCASE and lowercase Letters.
Since it is a layout trick, you are still free to revert to normal casing later on without the need to modify the source text.
The CSS involved reads like font-variant: small-caps.
