Is there a way to add CSS classes to common elements like Headers?

We have to create a lot of different forms and we would like to repeat some styles without having to identify each element by id. Is there a way to add css classes to a header or other elements?

This is an issue both for form entry and retrieval. If we programatically get the results from the API it would be nice to be able to classify different elements differently. I can see a lot of different use cases where this could be handy.

For example. We would sometimes like the output to be in 2 columns. So right now we've had to add hidden fields in the different sections (identified by header) to help identify what should be in a right column or a left column.

Yes, that is possible. You can try using the Advanced Designer for this, here's a screen capture sample:

After that, you can apply the CSS to other forms.

Is that what you're trying to ask? If not, please let us know.
