I want to make emoji bigger than the text that surrounds them. At my age and eyesight, it can be difficult to tell the difference between 😃, 😄, and 😊 when they are as small as the text.

Is there a way to use CSS to increase the font size of specific characters without having to wrap them in an extra <span> or similar?

Yes! Although it is a bit of a hack.

Graphics with scientific data become clearer when the colours are chosen carefully. It is convenient to have good default schemes ready for each type of data, with colours that are:

distinct for all people, including colour-blind readers;
distinct from black and white;
distinct on screen and paper;
matching well together.

This site shows such schemes, developed with the help of mathematical descriptions of colour differences and the two main types of colour-blind vision.
