Branding & Domains

Appearance & theming

Colors, fonts, presets, cover images, and dark mode. Make every form feel like a natural part of your brand.


Theme panel

Click Theme (palette icon) in the top toolbar. The panel docks to the right and previews changes instantly.

The Mode switch (Light / Dark) at the top of the panel changes which color scheme you are editing. Each mode stores its own theme values, so you can fine-tune both independently.

The Theme picker below it lists your workspace themes for that mode first, then the built-in presets. The footer shows All changes saved until you edit something; then Discard and Save appear.

Presets

The Theme picker carries seven presets for light mode and nine for dark. Each one applies a full set of coordinated colors, a font, and corner rounding in one click.

  • formbase default — applied automatically to every new form, one per mode

  • Presets — the curated themes listed below

  • Custom — “Only this form”. What the picker shows once you change any value by hand

Workspace themes

A workspace theme is a named theme for one mode, light or dark, that several forms share. Use one to keep every form on brand: change the theme once and every form that uses it follows. To theme both modes, keep two, such as Acme Light and Acme Dark.

Create a workspace theme

  1. Open the theme panel on a form, choose Light or Dark, and pick a preset or adjust the colors until the form looks right.
  2. Click Save as workspace theme under the Theme picker and give it a name, such as your company name.

That mode of the form is now linked to the new theme. The picker shows its name and how many forms use it.

Use it on another form

Open the theme panel on the other form, pick the theme under Workspace themes, and click Save. The picker only lists workspace themes for the mode you are editing, so link the light and dark modes separately.

Edit a linked form

A linked form edits like any other form. As soon as your changes differ from the workspace theme, the footer asks where they go:

  • Save to [theme name] updates the workspace theme and every form linked to it.

  • Save for this form only keeps the change on this form. That mode stops following the workspace theme and becomes a custom theme.

Applying a preset to a linked mode also unlinks it. To link it again, pick the workspace theme from the picker and save.

Published forms update on their next publish

Saving a workspace theme changes the draft of every linked form right away. Respondents see the new look after each form is published again, just like any other edit. Linked forms show Publish changes until then.

Rename or delete

On a linked form, open the ⋯ menu next to the Theme picker. Rename changes the name everywhere the theme is used. Delete removes the theme; forms that used it keep their current look as a custom theme.

Theme controls

Pick a preset or workspace theme, then fine-tune typography and colors. Each color describes a purpose rather than one component. For example, changing Text updates page text, question titles, field text, and option text together. Hover a color’s name to see what it controls. A dot marks colors you have changed but not saved.

Typography

SettingWhat it controls
FontTypeface for form fields, page text, and shared blocks. Eleven families, listed below
SizeBase text size, 12–22 px. Related labels and controls scale with it
Corner radiusShared corner rounding for inputs, cards, options, and buttons, 0–32 px

Colors

Colors are grouped by where they show up on the form.

The Rating group also has Star size, the size of Rating stars in pixels, from 12 to 48.

Fonts

formbase ships eleven font families. The font you choose under Typography applies to all text on the form.

Font familyStyle
Cal Sans UIDefault sans-serif for formbase
InterClean geometric sans-serif
ManropeModern geometric sans-serif
ArialNeutral system sans-serif
TahomaCompact sans-serif
Times New RomanClassic serif
GeorgiaElegant screen serif
LoraContemporary calligraphic serif
Palatino LinotypeBook-style oldstyle serif
JetBrains MonoDeveloper-friendly monospace
Comic Sans MSCasual hand-drawn

The cover image and logo sit at the top of the canvas. You set them up directly on the canvas — not inside the theme panel. For a walkthrough, see Understanding the editor → Cover and logo.

Dark mode

formbase supports dark mode in two places: the dashboard and published forms.

Dashboard

Toggle dark mode from the user menu at the bottom of the sidebar. The setting follows your account across devices.

Published forms

Published forms follow the respondent’s system preference by default. If their device is in dark mode, the form shows in dark mode.

Theming both modes

If you only set up a light theme, the form uses formbase’s default dark colors when dark mode is active. For full control, set up both color schemes using the light/dark toggle at the top of the theme panel.

When you switch between Light and Dark in the theme panel, the dashboard switches to match. This lets you preview your theme in context while editing.

Common theming patterns

  • Match your brand — pick your brand font, set the Button color to your primary brand color, and upload your logo. Use a preset as a starting point, then save the result as a workspace theme so every form shares it.

  • Dark-mode-first survey — force dark mode via the embed settings when sharing, then customize the dark color scheme for readability. Use a high-contrast accent for the active rating color so stars pop on dark backgrounds.

  • Minimalist embed — set the Background color to match your website, hide the cover image and logo in the embed settings, use a quiet Border color, and drop corner radius to 0.

  • Playful quiz — pick Comic Sans MS, push corner radius towards 32 for pill shapes, use a bright Selected color, and add a cover image from the Unsplash tab in the cover picker.

Branding

By default, published forms display a small formbase badge. Turn it off with Show formbase branding in Form settings → General. Removing the badge requires a Pro or Business plan — see plans & pricing.

Test both light and dark modes before publishing

Preview your form with system dark mode enabled before publishing. Logo contrast and accent colors often need a tweak for the dark variant — especially cover images and button colors that look great on a light background but wash out on a dark one.
