Thanks to the :target pseudo-class can be passed from one section to another. The animation of password error is connected via javascript but the animation is created using CSS3. Desktop Finally here we have in our desktop. For the rest is all CSS3 excluding the background image and icons. About this Project Modern Browser Supported HTML5 and CSS3
GameJs GreenSock | Homepage How to optimize your CSS Keeping your CSS files small and organized is very important, especially if you’re going to spend any time editing your site in the future, (or if others are gonna be using the code i.e. clients). Helpfully, there are a number of different techniques which can be utilized to aid organization and size of your CSS files in order to make them more streamline. Having more streamlined CSS will save you time and stress in the long run so it’s important to get it right. Firstly, keeping a single stylesheet, normally named style.css, is a good place to start in the organization of your CSS. Code in Style In order to keep your CSS files more streamline it is important to start by using a good code editor, such as TextWrangler on Mac, or Notepad++ on Windows.

While not really ready for prime-time on its own at this point, it can definitely be used in combination with tools like Modernizr (www.Modernizr.com). One of the first things you might do is create a home page with a simple navigation system on it. This blog post will show you one way to accomplish this. Navigation Figure 1 shows an example of a home screen and a navigation system. While there were ways to accomplish drop shadows, rounded corners and gradients prior to CSS 3 and HTML 5, it was not always easy for developers to do so.

kesiev/akihabara Tutorial: Building A Game In Edge Animate (Offender) Introduction: I’ve decided to build this first Tetrageddon Games “mini-game” tutorial, Offender, in Adobe Edge Animate because the program is still very new, and there isn’t much out there on it in terms of game development. I think this will make a great “getting started” resource for newcomers, as well as demonstrate the capabilities of Edge Animate. In this tutorial I hope to offer a solid example of building a game with the program. This is the first part of a series discussing HTML5 game development. * DOWNLOAD the source files here: Offender_HTML.zip * Play the finished game here: Offender HTML * Visit the website for it here: Note, Edge Animate is being used in some game projects already. * Space Invaders RPG. * Adobe’s Episode 10: Controllable characters in an interactive environment * Create animated game HUD with Adobe Edge Animate and Coherent UI (Part 1) In terms of HTML5 game development, there are many frameworks out there for making HTML5 games.
