Hi,
the reason is the way html works (but please don't compare with the buggy and limited Flash html rendering

):
the <a> element is an 'inline-element' and is only as width as its content is, therefore centering itself inside itself doesn't have much effect,
by using/adding this css code to the <a> css style code:
|
Quellcode
|
1
|
display:block; width:100%;
|
the <a> element will be rendered with 100% width of the parent element and then centering the text inside it will work.
Best regards,
Klaus
