Why learn to adjust colors and styling features with Javascript rather than HTML or CSS?

Currently on the Javascript & The Dom lessons.

Throughout the course you manipulate the colors of texts by changing them through .getElementById. Why not just change this through CSS or even HTML? Is this a better practice?

There isn't necessarily a need to do this in practice. This is just to demonstrate what can be done to properties with JavaScript and to get you thinking about what you can and should be doing with the DOM. Later on for example you'll be using the value property to change the text content of elements.

There's lots more fun things on the way :)

Ah, I see. Thanks for the input!
