If you export from Fireworks into clickable HTML prototypes, you’ll find that your exports are always left-aligned – even if you select center alignment during the export. This seems like a bug to me, luckily there is a fairly painless workaround.

Note: Tested in Fireworks CS5 on Mac, but should work approximately the same in other versions or Windows.

Open /Applications/Adobe Fireworks CS5/Configuration/HTML Code/Dreamweaver/SLICES.XTT and locate the following line: (line 662)

WRITE_HTML("<!--Fireworks CS5 Dreamweaver CS5 target.  Created ", d, "-->\n");

Now add the following right below it:

WRITE_HTML("<style>body {text-align:center;}</style>\n");

and BAM! You’ve got centered exports.
