If you’ve ever felt the need to wrap stuff around an irregularly-shaped image using CSS, you may have been somewhat disappointed to find out that it’s forced to wrap around the image’s bounding box, rather than the actual contents of the image.

jQSlickWrap is a jQuery plugin that works on HTML5 Canvas element and enables you to easily and accurately wrap your text around the content of floated images.

It implements a client-side version of the Sliced and Diced Sandbags method of wrapping text around an irregularly-shaped object. In case user’s browser doesn’t support slick text wrapping, it will gracefully fall back to simple wrapping.

Superfun creates a Lightbox gallery with HTML5 Canvas element and CSS3. It allows for AJAX injection, SWF content, iFrame content, and utilizes the new CSS3 transform property to mimick a Flash environment, while completely avoiding Flash.

Though its not as powerful as we see around but consider this a first step and an HTML5, CSS3 experiment (successful experiment to me) with scale, rotation and transformation.

Google Browser Size is a visualization of browser window sizes for people who visit Google. For example, the “90%” contour means that 90% of people visiting Google have their browser window open to at least this size or larger.

This is useful for ensuring that important parts of a page’s user interface are visible by a wide audience. And designers can use this tool to get better insights and user experiences for their websites and applications.

In the above example image, there is a donate now button which falls within the 80% contour, meaning that 20% of users cannot see this button when they first visit the page. 20% is a significant number; knowing this fact would encourage the designer to move the button much higher in the page so it can be seen without scrolling.
