Using CSS selectors are the bread and butter of HTML and CSS coding. You have to think about what elements on your page you want to target and how to write rules that cleanly target and apply css styling to those elements.

2 good rules you always want to follow: don't make rules more specific than they have to be (but also don't make them overly generic like "target every div on a page"), and also don't repeat yourself (DRY).

$Modular Javascript - Prototypal Pattern vs Classical OOP in JS While many JS devs still use classical OOP, many have switched to the prototypal pattern for Module Inheritance and Instantiation. Heres the prototypal pattern for JS and why some devs find it simpler to use. View Classical Inheritance here: https://www.youtube.com/watch?v=sWOXYDBbz0g View the whole modular JS playlist here: https://www.youtube.com/playlist?list=PLoYCgNOIyGABs-wDaaxChu82q_xQgUb4f SOURCE CODE HERE: http://codepen.io/anon/pen/gaggvG?editors=001 Basically, when coding JS OOP with the prototypal pattern, everything is an object. You start with an object literal and, then, to inherit from it, you use Object.create(someModule) to create a child that inherits from it. var parent = {some: method}; var child = Object.create(parent); //now add new methods to the child child.newMethod = someMethod; So theres really no difference between inheritance and instantiation in the prototypal method. To create multiple children, simply: var child1 = Object.create(parent); var child2 = Object.create(parent); And there you have it! Also see the source javascript code on how to include a create method so creating is a little more seamless. -~-~~-~~~-~~-~- Also watch: Responsive Design Tutorial - Tips for making web sites look great on any device https://www.youtube.com/watch?v=fgOO9YUFlGI -~-~~-~~~-~~-~-$
