Design and templates

Change colors, fonts and spacing

Make your help center feel like your brand: set its colors for light and dark mode, pick the fonts, and choose how roomy the layout is. The preview updates as you go, and visitors see the result once you publish.

Change colors, fonts and spacing

  1. In the template editor, open the Theme tab (⌘2).

  2. Under Light mode, click the swatch next to Primary and pick a color, or type a hex code such as #24644f.

  3. Under Typography, choose a Heading font.

  4. Under Layout, set Density to Compact, Comfortable or Spacious.

  5. Check the preview in both Light and Dark appearance, then click Publish.

Screen recording. In Theme, type a new Primary color or click the swatch. Pick a Heading font. Make the layout roomier with Density.
A new primary color, heading font and density in a few clicks.

Your colors

Light mode and Dark mode each have their own set of seven colors. Visitors see the dark set when they view your help center in dark mode.

Color

Where it's used

Primary

Your main brand color: buttons, links, highlights and the hero background.

Accent

A second brand color. The hero's default gradient runs from Primary to Accent, and a few small labels use it.

Foreground

The main text color.

Background

The page background.

Surface

Cards, panels and other raised areas.

Muted text

Secondary text such as breadcrumbs, dates, descriptions and footer text.

Border

Dividers and outlines.

Colors stay readable automatically

Your colors are used exactly as you pick them for buttons, bands and backgrounds. Where a color is used for text, HelpCenter.io checks that it's readable and, if it isn't, makes it only as much darker or lighter as needed:

  • Muted text is kept readable on your background and surface colors.

  • Text on buttons filled with your primary color turns black or white, whichever reads better.

  • Links and labels in your primary or accent color are adjusted when they'd be too faint as text.

  • Outlines of text fields are kept clearly visible.

So if a text color on your live site looks slightly different from the one you typed, that's why. See How accessible is my help center? for more.

Your fonts

Under Typography, set three fonts:

  • Body font for your articles and most text.

  • Heading font for titles and headings.

  • Monospace font for code.

Each list starts with popular fonts such as Inter, Roboto, Lora and Merriweather. For more, click Browse all…, search by name or filter by Sans-Serif, Serif, Display, Mono or Handwriting, and click Use on the font you want.

Fonts load from Bunny Fonts (fonts.bunny.net). On a slow connection, text can show in a fallback font for a moment while your font loads. That's normal.

Spacing and corners

  • Density sets the space between and inside sections and cards, and the size of page titles. Compact fits more on the screen; Spacious gives everything more room.

  • Radius small, Radius medium and Radius large set how round the corners of fields, buttons, cards and panels are. Enter a size such as 8px, or 0px for square corners.

Planning to try other themes? Do that first. Applying a theme replaces your colors, fonts, corners and density unless you untick them. See Choose a theme.

Troubleshooting

My help center still shows the old colors. Your changes are in the draft. Click Publish, then refresh your help center.

Dark mode looks wrong. Dark mode uses its own colors. Set them under Dark mode, and switch the preview's Appearance to Dark to check them. See Light and dark mode.

My logo disappears on the dark background. Upload a light version as your dark-mode logo. See Add your logo, favicon and brand name.
