Css and javascript confusion on my part

Coffee Lounge
#1

I am clearly too stupid to understand this article because I do not have a clue what they are on about.

Is there actually any debate that css should not be used at all and replaced by javascript?
If so how would that even work, or am I reading this article wrong.

I am more of a php / mysql backend developer than I care to admit and have very limited javascript knowledge, but do know html and css well too for front end, which bootstrap helps with tremendously. So the crux of my question is, I never imagined replacing css with javascript for even a moment, is this even possible and is there any reason or big advantage in using javascript instead of css.

A browser can interpret the trinity of HTML, CSS and JS with each having its own function.

If we use JS (interpreted by the browser) to create CSS (interpreted by the browser), it is like travelling from New York to Los Angeles via the North Pole.

Add to that, the continual changes to CSS , e.g. the calc() function, the transform property and srcset attribute, we are continually diminishing the role of JS.

So, no, there should be no debate that CSS should be replaced by JS while in fact the opposite is true (my opinion).
