just give more details
You should learn JavaScript (ECMAScript 5) to be clean/fluent as well have an easier time when it comes to learning. HTML/CSS are injected but it's not till you've hoisted queries within the document.
Pro-tip: WSSLoad = On document start, you should check for WSS and define when it is loaded! DOMLoad = Doesn't load on start so we run an interval to determine when the page has loaded. Could loop 3 - 7 times before seeing the page has loaded FullLoad = Checks for both WSSLoad and DOMLoad to initiate the script to the fullest otherwise in some browsers you error right out.
Set scripts to run at document-start and if done right, no issues at all. You may document-end load if it's just DOM work and you don't plan on WSS; less setup to script.
