Laying the groundwork: integrating and getting started with the styler
Add your Fluent Forms form to Gutenberg
To get started, forget about obscure and complex shortcodes. The first essential step is to integrate your form directly into the Gutenberg editor. This is the only way to gain complete visual control over your layout.
The procedure is simple: click on the Plus (+) icon, search for the “Fluent Forms” block, and add it to your page. Once the block is in place, a drop-down menu appears to select the desired form. It is then immediately displayed in a live preview before your eyes.


This is the absolute basis for any visual customization. This approach is much more intuitive than older methods. In fact, with Fluent Forms, the essential form plugin, everything becomes fluid.
Finding the styling tools: the Gutenberg Block Styler
Once you have selected the Fluent Forms block, look at the right sidebar of the editor. This is where you can customize your Fluent Forms Gutenberg form using the Gutenberg Block Styler.

This styler is cleverly organized into three tabs: General, Misc, and Advanced. Focus on the first two to create your design without code. Leave the third tab to developers, as it manages technical CSS, which we will avoid here.
Apply a quick style with predefined templates
For those in a hurry, Fluent Forms offers ready-to-use styles. This is a great starting point to save time without sacrificing aesthetics.
- Modern: A clean, contemporary design.
- Classic: A more traditional style that has proven itself.
- Bootstrap: For seamless integration with themes based on this framework.
- Inherit: The form directly inherits the styles from your WordPress theme, ensuring perfect consistency.
- Custom: The starting point for creating your own design from scratch.

Customizing form elements: the General tab
Now that the form is in place, let’s get to the heart of the matter: customizing each individual element using the ‘General’ tab.
Modify labels and help texts (placeholders)
Labels are your first visual cues. The “Label Styles” section allows you to customize your Gutenberg fluent forms by changing their color and typography. Adjust the font and weight for a seamless integration with your brand identity.
Next, adjust the “Placeholder Text Styles.” Set a custom color for this help text, which is often too pale by default. This instantly improves readability while matching this detail to the overall design of your page.

Refine the appearance of input fields and checkboxes
Go to the “Input Field and Text Field” section. This is where you customize the appearance of the fields where the user writes.
Refine the rendering: text color, background color, typography. You can also play around with borders (color, thickness, radius) and add a drop shadow to give it some depth.
Clearly distinguish between the Normal state and the Focus state (when clicking in the field). This difference creates a clear visual cue for the user.
Gone are the days of juggling bits of CSS to align a button. With Fluent Forms’ Block Styler, everything happens visually, right in Gutenberg.
Adjust the submit button to encourage action
The submit button validates the conversion. It is fully customizable: manage its alignment (left, center, right), width, and text and background colors.

You can also control the padding to space out the text and margins, and, most importantly, define a distinct hover style. This interactive detail is crucial to the user experience.
Customize the form as a whole: the Miscellaneous tab
Manage the container: background, borders, and spacing
Now let’s move on to the “Container Styles” section. To customize the Gutenberg Fluent Forms form, this feature acts as a box surrounding your form, which is essential for integrating it visually without it floating in a vacuum.
Here are the options available to transform this raw box into a consistent design element. Take a good look at this table, because ignoring these settings (loss aversion) often makes forms unreadable or poorly integrated on mobile devices:
| Option | Description |
|---|---|
| Background | Allows you to set a solid color, gradient, or background image for the form. |
| Allows you to set a solid color, gradient, or background image for the form. | Adds space inside the container, between the border and the fields. |
| Margins | Adds space outside the container, to move it away from other elements on the page. |
| Border | Allows you to draw a frame around the form (color, thickness, style). |
| Drop shadow | Apply a shadow under the form to give it a depth effect. |
Customize feedback messages: success and error
The user experience doesn’t end when they click “Submit.” It’s essential to pay attention to the “Success Message After Submission” section. Poor visual feedback can leave your visitors in doubt, which undermines trust.

Here, you can change the background (often green by default), alignment, and text color. Also, configure “Error Messages” carefully: a clear and visible warning is essential to guide the user without frustrating them unnecessarily.
Pay attention to the finishing touches: asterisks and other details
Finally, open the “Asterisk Styles” section. The default small red symbol may clash with your design. Change its color to soften it or align it perfectly with your graphic charter.

Don’t underestimate these micro-adjustments. It’s the accumulation of these precise details that transforms an amateur DIY project into a professional-looking form capable of reassuring any prospect.
Beyond aesthetics: best practices for form design
Mastering the tools is good. Knowing why and how to use them to create an effective form is even better. Let’s look at some design principles.
Ensuring accessibility: the role of contrast and typography
When customizing Fluent Forms Gutenberg forms, never sacrifice accessibility. Use color options to ensure sufficient contrast between your text and the background. Light gray text on a white background looks elegant, but it’s unreadable for many people.
The choice of typography is just as important. Opt for a legible font and a comfortable size, with 16px as a baseline, because design must serve function. This principle is integrated into the WordPress site editor (FSE).
Create a visual hierarchy to guide the user
A good form naturally guides the eye. Use the padding and margin options in the “Miscellaneous” tab to create logical groupings. This effectively breaks up the form.
The drop shadow on the container makes it stand out clearly on the page. Similarly, larger or bold typography for section titles helps the user navigate. It’s a simple but powerful trick.
Don’t neglect hover and focus states
Remember that interactions are key. The style should not be static.
Set up a distinct style for the “focus” state of fields and the “hover” state of buttons. This visual feedback confirms to the user that the interface is responding to their actions. A simple thicker border or a subtle color change is enough. It’s a detail that makes all the difference.
A well-designed form isn’t just prettier. It guides the user, reduces friction, and directly increases your conversion rates. Every styling detail counts.
You now know how to visually customize your Fluent Forms directly in Gutenberg. By applying these settings, you can transform a simple contact tool into a real conversion lever, without a single line of code. Take the time to test the final result: a polished design immediately builds trust.
