Relative units is relative to something, screen size, parents... Absolute size does not change, no matter what. For responsive desing is more suitable use relative units. But it's not a rule. You may use absolute size sometimes.

Media queries can be used to apply different styles based on the screen size to make your web page responsive and compatible with all devices and screen resolutions and it's a good way to scale fonts. Like in the example on the left you can specify the font size in each media query that have a specific width size. But you may ask what the default screen resolutions that I should use? The answer is there is no default resolution for screens, but there are some commonly used breakpoints, And here some breakpoints for widths of devices screens: 320px — 480px: Mobile devices 481px — 768px: iPads, Tablets 769px — 1024px: Small screens, laptops 1025px — 1200px: Desktops, large screens 1201px and more —  Extra large screens, TV

The calc() function is a very useful function that can help you make a more dynamic and responsive web design, and it can be very helpful for scaling fonts. The calc() function can let you mix two font units, one of which is fixed and the other is relative, and by doing so, you can scale the fonts in a perfect way, whatever the screen size is! EX: font-size: calc(10px + 2vw); You may ask why we mixed the units? Why not just use a relative font? Because sometimes when we use a relative font unit alone, it may look good on a big screen, but it will look very small and unreadable on a smaller one.

We have found clamp() to be an excellent way to scale our font-sizes. Since we normally have a mobile and desktop design, we know our max-min widths and fonts. There are simple web applications that allow you to plug those numbers, it then converts it to rem, and you are ready to go with responsive fonts.

PX (pixels) and VW (viewport width) are units of measurement used in HTML and CSS to define the size of elements on a web page. PX is a fixed unit of measurement that refers to the size of a pixel on a screen. It is commonly used to specify the size of text, images, and other elements on a web page. VW, on the other hand, is a relative unit of measurement that refers to the width of the viewport, or the visible area of a web page. It is commonly used to create responsive designs that adapt to different screen sizes.

To scale fonts on a website for responsive design, use relative units like `em`, `rem`, or `%` instead of fixed `px`. Employ CSS media queries to adjust font sizes based on screen width or device type. You can also utilize viewport units (`vw` and `vh`) and techniques like "fluid typography" with `calc()` for proportional scaling. Responsive design frameworks and libraries can simplify font scaling, and allowing users to adjust font size preferences enhances accessibility. Comprehensive testing across devices ensures readability and aesthetics.
