style guide for javascript code example

Example 1: javascript Name convention

// camelCase 
//The general rule is to start variable, function and method names 
//with a lowercase letter, class and object names with a capitalized letter, 
//and constants are typically all caps. 
//Follow these conventions, and your scripts will 
//be consistent with what others are doing, and much easier to understand.

Example 2: javascript style an element

// Getting the element first
var myElement = document.querySelector("#myElement");

// examples for updating styles
myElement.style.color = "blue";
myElement.style.backgroundColor = "red";

Example 3: style through javascript

element.style.backgroundColor = "red";   // set the background color of an element to red
