Version 4.xx introduced some style changes.
Version 4.xx, introduces more style settings for Style of labels, field inputs, buttons, and text.
Version 4.xx has a new improved Styles settings tab. The style settings are now divided into “Alignment DIVs”, and “Style of labels, field inputs, buttons, and text”.
“Alignment DIVs” settings are for adjusting the alignments of the form elements. You can also check “reset the alignment” to return to defaults and make the “labels on top” or “labels on left”.
“Style of labels, field inputs, buttons, and text” settings are for setting style of the form labels, field inputs, buttons, and text.
This is a great way to change label or field colors. For example, you can add color:green; to the “Field Labels” settings if you want (or any other color).
