A slice’s options determine how the content of the slice will look and function in the resulting web page.
Select a slice in the illustration window, and choose Object > Slice > Slice Options.
Double-click a slice in the Save For Web & Devices dialog box with the Slice Select tool.
To
edit the text for HTML Text slices in the Slice Options dialog box,
change the slice type to No Image. This breaks the link with the
text object on the artboard. To ignore text formatting, enter <unformatted>
as the first word in the text object.
