If you use the Divi theme, you probably already know that you have access to incredible styles for contact forms and all elements.
While Divi has a great builder for contact forms, many people seek out Gravity Forms, known as a premium plugin, which goes beyond a simple contact form. Gravity Forms has integrations with many other CRM tools and 3rd party service providers and proves to be powerful, scalable and reliable.

The add-on prevents the headache of having to manually copy and paste styles and attempt to match them. The plugin makes the matching process effortless and save you a lot of time and unnecessary stress. It seamlessly matches the Gravity Form style to the Divi style. In addition to matching the two styles, it also provides responsive styles to Gravity forms.
The responsive style feature allows for complex forms, halfs or third fields, to look great on mobile formats as well.The Surbma Divi & Gravity Forms add-on is lightweight with minified CSS to minimize loading time to as low as possible. The plugin is simple, easy to install and easy to use. Reviewers of the add-on say that it delivers exactly as promised.
Surbma, the creator of the plugin was inspired to make the plugin out of his love for Divi and his hopes that websites are beautiful, fast, secure and optimized for search engines.
Surbma offers a variety of other WordPress plugins, all of which are free. The Surbma Divi & Gravity Forms plugin is also free, but you will need to have purchased the Divi Theme and the Gravity Forms Plugin.
