The ColdFusion Flash form tags have a style attribute that lets you specify control characteristics using CSS syntax. You can specify a style attribute in the following tags:
cfform
cfformgroup
cfcalendar
cfformitem, types hrule and vrule
cfgrid
cfinput
cfselect
cftextarea
cftree
The attributes for the cfform and cfformgroup generally apply to all the form or form group's children.
Flash supports many, but not all, standard CSS styles. ColdFusion MX Flash forms only support applying specific CSS style specifications to individual CFML tags and their corresponding Flash controls and groups. You cannot use an external style sheet or define a document-level style sheet, as you can for HTML format forms.
