The HTML5 test score is an indication of how well your browser supports the upcoming HTML5 standard and related specifications. Despite these shortcomings they hope that by quantifying the level of support users and web developers will get an idea of how hard the browser manufacturers work on improving their browsers and the web as a development platform.

The HTML5 test score is calculated by testing for the many new features of HTML5. Each feature is worth one or more points. Apart from the main HTML5 specification and other specifications created the W3C HTML Working Group, this test also awards points for supporting related drafts and specifications.

Some of these specifications were initially part of HTML5, but are now further developed by other W3C working groups. WebGL is also part of this test despite not being developed by the W3C, because it extends the HTML5 canvas element with a 3d context.

jQuery Image Scroller Plugin creates a scrollable interface to scroll over a large image in a smaller area. The idea is that we have a container with a fixed height and width, an image that is taller than the container, and a container for the thumbnail of that image.

Once the plugin is applied, there is a span with a class of indicator appended to the small preview area which represents the area you can drag up and down.

PaintbrushJS is a lightweight, browser-based image processing library that can apply various visual filters to images within a web page.

You use it by applying a class to an element on the page and setting a few parameters with some extra HTML attributes. If the element is an img or it has a background-image set in your CSS, PaintbrushJS will create a temporary canvas element and manipulate the image there, before finally saving it back out to the original element. You can check out PaintbrushJS in action here.

Requirements: Does not work in IE8 or lower
