Rotating a Div Element in jQuery


Trying to rotate a div element...This might be DOM blasphemy, could it work possibly with a canvas element? I'm not sure - if anybody has any ideas of how this could work or why it doesn't, I'd love to know. Thanks.

Html5 Canvas vs SVG vs div



What is the best way for element creation on the fly and being able to move it around? Let's say I want to create rectangle, circle and polygon then I want to select the objects and move it around





And how is the performance of those three while in use for showing a web page? Let's say I want to create three visually identical web page and have header, footer, widget and text content in them. The first one is created using full canvas, the second is created using svg, and the third is created using plain div html and css.





Thanks in advance
