fix font size on wikipedia

page: https://en.wikipedia.org/wiki/Obama
problem: font is too small
culprit: font-size:calc(1em * 0.875);

This is a partial fix: calc is unsupported, so the above declaration should be ignored completely,
but instead it sets font-size to that of a parent, so this code doesn't work as intended:
font-size:0.875em;font-size:calc(1em * 0.875);
