I have added the YT_Columns short code with a image in the left column and text in the right column. That works okay but when I shrink the width of the browser window the contents of the two columns will always show next to each other. This looks very bad on mobile phones as the text column is then only a few characters wide. I would like the same behaviour as on your YT_Animation sample page. There you have an image and text in two columns and when viewed on a mobile the text automatically moves below the image. How do I achieve this??

Cheers
