Originally my default font had the size of 12 pixels (which is approximately 10 points, the standard size used in newspaper printing – I’m a retired journalist, that’s why). Most popular browsers use a 16 pixels letter as their default font. To decrease this to “my” 12, in my stylesheet I downgraded the body font to 75 percent. This downgrades “1em” from 16 to 12 pixels. Furthermore I changed all the pixel values for fonts used inside the body to em, so “12px” became “1em”, “10px” is now “0.835em” et cetera. Note that an a-link not having the href-attribute, does not automatically change the mouse cursor into a pointer!
