Is it possible to use custom CSS styling for the forms we create to increase the competitive appeal of OneBox OS

Here is an example of the form as is: https://icoloronebox.crm-onebox.com/form/0/6/ I insert such a form on my site, screen 1182. Here you can see that this form looks a little detached from the general design: https://icoloronebox.org.ua/products/license/ Please let me know if it is possible to customize the form with your own CSS style, so that the form fully corresponds to the design of the site, where we insert such a form: - headings; - text; - buttons, etc. If possible, where exactly. If you can't, because OneBox's own styles are used, then give a rating to improve it. When it becomes possible to adapt the design of forms to the site, it will give the operating system significant advantages over competing solutions. [file]18074[/file]
