Hey @armanism,
The issue previously was caused due to Theme Styling overwriting the form styling.
Currently we don’t have any plans to release a full-blown form style editor. I do agree it would be super helpful, though. I’ve made a note of the feature request and we’ll keep it on our radar as we plan out our roadmap for the future.
However, we do realize that having the ability to style items in this manner is preferred by some users, so we partnered with CSS Hero and have full support. You can learn more about CSS Hero here.
Of course, CSS Hero can be used site-wide, not just for your contact forms. It’s a super handy plugin and lets users avoid touching any code.
If you’d like to see how CSS Hero works with WPForms, you can check out the Live Demo option on their site.
So at the end of the day, instead of reinventing the wheel and building our own editor, we decided to partner with someone who is already an expert when it comes to frontend style editors.
I hope this helps!
