Couple of interesting discussions.
I had a button which had to toggle between Spin Start and Spin Stop text. When I implemented this in JQuery Mobile after the first press the button and text sizes became smaller. Then I came across this fix given in
I did the fix suggested by Hexagonal
$('#svbutton .ui-btn-text').text(currentTimeString); which worked like a charm.
I wanted to have the title, Spin, Info and Settings button in the header. Unfortunately this is not possible as described in this discussion
So I had to move the Spin button to the Content section.
