What you should know

“

- [Voiceover] Here's what you should know coming into this course. HTML and CSS are the tools of the modern web designer, so I expect that you know these pretty well, and don't need a refresher. You should also know at least a little bit of JavaScript. It doesn't mean you need to be a professional JavaScript developer or anything like that, but you should've seen it, and you should know some of the general concepts like what a variable is, what a function is, and that you can work with events to respond to user actions, that sort of thing. Depending on the way that you're going to use jQuery, you may not need to know a whole lot of JavaScript at all, but understanding a little bit of what it looks like and how to use it, to a limited extent at least, will serve you very well in this course, and make the examples easier to understand. One other big piece you'll need to be familiar with is the Document Object Model, or DOM. The DOM is your way of accessing the outline of a page. All of the elements you've written out in your HTML are collected up by the browser, laid out visually and programmatically, and then the DOM is your programmatic interface provided by the browser to let you access all that stuff through JavaScript, and, therefore, jQuery. It's a collection of methods and properties that you can use to get into each of those elements. With jQuery, you'll be using the same CSS you already use to style elements to find them on the page for programmatic use. If you feel a little dicey in any of these areas, I have some course recommendations to help bring you up to speed. For HTML, you can check out HTML Essential Training. For CSS, check out CSS Fundamentals. For JavaScript, there's Introducing the JavaScript Language. Then for the DOM, you can check out JavaScript: Enhancing the DOM.
