Plupload v1.0

Easy is a CSS/HTML/JavaScript framework started as a personal project and then grew into something more. The idea behind it is to reduce the amount of time spent on setting up the basic master HTML template by reusing the same coding techniques.

In this post we have a selection of jQuery plugins and tutorials for enhancing and aiding in the development of the dreaded form area. There are the always important validation plugins, plugins that will give the form added functionality (stretching text-areas, auto-tabbing...) and also plugins that will help you to style the form exactly as you need...and more.

Ever wanted those flash iPhone on/off toggle switches on your webpage? Love jQuery? Well then I've got something special for you. iphone-style-checkboxes implements the iPhone toggles as replacements for standard HTML checkboxes. Simply run the script and your site will be updated with these specialized controls. Best of all, the underlying checkbox is not touched and backend system will never know the difference. The change is purely visual.

Accessible data visualization in HTML has always been tricky to achieve, particularly because elements such as images allow only the most basic features for providing textual information to non-visual users. A while back, we wrote an article describing a technique we came up with to use JavaScript to scrape data from an HTML table and generate charts using the HTML 5 Canvas element. The technique is particularly useful because the data for the visualization already exists in the page in structured tabular format, making it accessible to people who browse the web with a screen reader or other assistive technology.
