Form edits don't reflect in the preview.

I have another question. I'm trying to customize the forms attributes, size, color, width, height of fields, etc. After I save it still doesn't seem to change anything when I preview the form. Do i need to upgrade to another plan to get it to work?

Could you please indicate what is the form where the edits you have applied don't reflect in the preview? Any edits should reflect immediately when you preview the form. Please try clearing forms cache: https://www.jotform.com/help/229-How-to-Clear-Your-Form-Cache 

It's the pastel theme I used for my form. I go to form designer and then advanced css editor and when i change the size of fields and edit parameters the form remains exactly the same after I save and preview. I'll see the fields temporarily change and once i move my cursor away from the edit box it goes back to it's original form.

 

I cleared the cache and browser history and still nothing.

Is this the form in question? https://www.jotform.us/form/90727266692164 

If you applied a theme on the form, the CSS that belongs to that theme is forcing it to keep the original style, that's why the edits that are done in the designer do not work.

Please illustrate with screenshots the customizations that you would like to apply, so we can try to do it through CSS injection: https://www.jotform.com/help/117-How-to-Inject-Custom-CSS-Codes
