We recently put together a list of links and references that would be useful for anyone interested in getting up to speed on HTML5 development. These are what we consider to be the absolute basics -- what you need in order to even begin discussing more complex issues of architecture, tiering, data-binding, MVC and so on. So, imagine you are participating in an HTML5 course at Encodo -- you'd probably get something like the following article in order to make sure you're ready.

HTML5 prerequisites

This section describes the knowledge prerequisites for course participants.

Since the course includes a significant hands-on component and will discuss the advantages and disadvantages of architecture-level concepts, a minimum level of proficiency in some basic topics is required.

  • Prerequisites include online resources that can be used to gain the minimum required level of proficiency. The resources are there to help participants learn about a topic. Participants that are already familiar with a topic do not need to use them.
  • Familiarity means I know what CSS selectors do and know a few of the basic ones. It does not mean I know every CSS selector by heart nor does it mean I read an article about CSS five years ago. Participants are expected to judge their own proficiency honestly and prepare accordingly.
  • Required resources are generally a few pages that can be read in 1015 minutes. Optional resources are helpful for learning more but arent required reading.

HTML/DOM

The DOM (Document Object Model) is the data structure on the client side that is rendered in the browser. A participant must be familiar with the basic tags and structure of the DOM as well as common attributes and events, including which ones are new to and deprecated in HTML5.

Required:

Optional:

CSS

Participants must be familiar with the basic syntax and units. A working knowledge of how the basic selectors are applied to elements in the DOM is also required. Knowing how style cascade and override other styles (specificity rules) is a plus.

Required:

Optional:

JavaScript

It is assumed the participants will be proficient in at least one programming language. An awareness of the common pitfalls and quirks of JavaScript is required: that it is untyped, has a very loose definition of objects and inheritance, and that web apps written in it tend to be quite functional and event-based in nature.

Required:

Optional:

jQuery

jQuery is an industry-standard library that binds HTML, CSS and JavaScript. Participants should be know how to use jQuery selectors use a CSS-like syntax to select elements from the HTML DOM, attach events to those elements and traverse to other elements in the DOM (e.g. children, siblings, etc.).

Required:

Optional:

Browser compatibility

All modern browsers support the basic features outlined in the sections above. The site http://caniuse.com/ is useful to for finding out on which browsers the more advanced features are supported.

Practice sites

The following sites provide online sandboxes where participants can enter HTML, CSS and JavaScript to test it without installing or executing anything. They all allow examples to be saved for sharing.
