HTML, CSS and Js

 This is impressive and help to understand in 1/3 of the time.

And is that we write some in HTML and in JS inside "", let me say that others aren't write inside "", let me give a valid reason, some times we separate some of the rest because isn't from there, and they came from other of the languages, so if something is an attribute from CSS inside the HTML it will be between "", so sometimes you are in the JS and a number is between "", and isn't a string but to be an attribute from the CSS for the JS is a string and will travel to the CSS context language and treat proper like a number so isn't inside the JS that will operate properly because there is a string.
