Jquery Mobile nicely lays out controls in a grid. I would the text “12345678” outlined in red in the image below to sit right above the textbox and left aligned. I can’t see how to do it.

The image was generated with this jsfiddle: http://jsfiddle.net/958Gr/3/
By setting disabled=’true’ and value=”12345678″ you can get something decent. The account number will still show as as field, but then you can theme it differently. See this fiddle:

Good Luck!
