CSS JavaScript

Please tell me. First is in the same page. css at the top. js comes second. What is the loading order?

mrc is the id of a certain div. The css height of this div is set to 50px.
Why is document.getElementById("mrc").style.pixelHeigh initially 0?
document.getElementById("mrc").style.heigh is actually an empty thing?

Is it a loading order problem?

Reply to discussion (solution)

js must be run at least after the div is loaded

css first in js

css first, then js



js must be run at least after the div is loaded

js loading is synchronous, CSS loading is asynchronous.
