Funció que agafa les mides de la pantalla i redimensiona proporcionalment una imatge per a que s'adapti a ella.

I've previously posted this here: http://snipplr.com/view/59044/flexible-site-layout-with-resize-detection/

This new version is short and more efficient, plus it no longer shows 1 (harmless) error on launch. Works the same as last time, the sizable object has the size to add the class too all the sizable elements, so for this example if the screen is less that 450px it'll add the class "phone" to the body (and the other elements), and if it's larger than 750px, but not 1000px, it'll give it the tablet layout. More information about the script is at the link, questions/comments/concerns can be sent to be from here or the comments section at the link.

Still problematic...

1. The source of the iframe content must reside on the same domain
2. if the content inside the iframe changes height, this won't adapt
3. I left Google Analytics code off the demo above, as when I added it in it seems to interfere and not resize the iframe, despite seemingly generating no errors.

Resize a rectangle (ie.: an image) while keeping the aspect ratio, without float.

You can scale up and down the proportions so the edges will be either at most or at least the given one.

Use this snippet to get the native image size of an image if it is resized with CSS or IMG attributes. Requires jQuery.
