title: how to set font size based on container size?
body: <p>I have a container that has a % width and height, so it scales depending on external factors. I would like the font inside the container to be a constant size relative to the size of containers. Is there any good way to do this using CSS? The <code>font-size: x%</code> would only scale the font according to the original font size (which would be 100%).</p>
