"-" font sizes

[Adam P.]

Why are there "-" font sizes? -2 is the same as 1, and -2 through -7 are all the same. I don't get it.

1, 2, etc. are absolute font sizes.

"-" and "+" designate relative sizes. Relative to the size set in your browser preferences.

I believe 3 is the default browser font size, which is why the absolute size of 1 and the relative size of -2 are the same in your browser. Since 1 is the smallest font possible (unless you use CSS and designate font size by points, pixels, etc.), that makes -3 and smaller designations ineffective.

I like the text to be the size I designate, so I always use absolute sizing. Of course that can be overriden in the browser preferences, but most people just accept the intended size.

I would advise to stop using the <font></font> tag in all your code and use stylesheets instead.

For setting your font size css is more precise as it uses pixels to determine the size.
