Hi,
You can customize the styles of the description field by using a CSS style like the following (example for changing its color):
#formheader_1 span { color: red; }
There is more info about the styles and design in the following FAQ: https://apphourbooking.dwbooster.com/faq#design
For further customizations, please note that the ability to paste directly custom HTML into the form builder is a feature available in the commercial versions of the plugin. We’d like to help but we can’t reply about that in this forum. We are not allowed to support any customers in these forums.
For pro or commercial product support please contact us directly on our site. This includes any pre-sales topics as well.
Commercial products are not supported in these forums. We will happily answer this and any other questions you can have on our own site.
Thank you for using the plugin!
