Chrome and all other chromiums render HTML code before JS is processed. As a result, some elements twitch. How to fix?

Question

JavaScript

This is not the case in FF and IE.............

Answer 1

1) Do not use JS for layout!
2) Or, if you are writing a SinglePageApplication (in Angular, Backbone and others), hide, for example, the active area before it is processed by scripts; instead, show a loading spinner or something like that.
