Any difference between a.button and button.button?


I put a list of buttons inside a ui-sortable directive, you can see it works fine if I use <a> tag but not if I use <button>. The drag gestures seem to be blocked by <button>.

Anyone know the reason? Is there any difference between<a class='button'> and <button class='button'>?

@ybian, please take a look at those links:

@meni Great! Thanks a lot!
