Appearance · 1zero

Settings → Appearance sets how the browser looks. The theme and background are shared with every 1zero app on your computer, so a change here shows in 1zero Code too, and the other way round.

Theme

Mode is System, Light, or Dark. System follows your computer.

Palette picks the colors. There are 13 built in:

Default, Graphite, Caffine, Light Green, Twitter, Cappuccin, Leadgen, Amber Minimal, Clean Slate, NBT Red, Dark Star Purple, Red Earth, and Midnight Amethyst.

Moving through the Palette menu previews each one in the browser's windows. Nothing is saved until you pick one.

Settings → Appearance → Custom themes lets you make your own. New theme opens a designer where you set the colors for light and dark separately. Your themes show in the Palette menu after the built-in ones.

Export… on a theme saves it as a file, and Import… loads one, so you can pass themes around.

Background

An image across the top of the home page. Choose a picture or a video from your computer: PNG, JPEG, GIF, WebP, AVIF, SVG, MP4, or WebM. GIFs and videos play on a loop, muted. The file stays where you keep it; the browser doesn't copy it. Recent images lists the ones you've used before, so you can go back to one.

Setting	What it does
Height	How much of the page the image covers, from the top
Blur	Softens the image
Tint	Blends the image toward the theme's background so the page stays readable
Fade length	How much of the image fades into the page at its bottom
Fade	How the image eases into the page. Vignette fades its sides too.
Focus	Which part stays in view when the image is cropped: Top, Center, or Bottom
Show on the home page	Off keeps the image and its settings for later
Show on the browser's pages	Also draws it behind Settings, History, Downloads, and Plugins, blurred and tinted so text stays readable

Changes apply to decides who sees a change. All 1zero apps changes the shared background. Only 1zero Browser changes just the browser's home page, leaving your other apps as they are. Use shared values drops the browser's own changes.

Home page

The order of the home page's parts. Drag them into the order you want. See Home page.

Pages and fonts

Page zoom sets how large web pages are drawn. It applies to open tabs right away.

Fonts sets the font size, the standard, serif, sans-serif, and fixed-width fonts, and a Minimum font size that no text goes under. The browser's own pages follow these at once. Web pages use them for text they don't style themselves, from the next tab you open or wake.

Title bar

Setting	What it does
Fade window controls	The close, minimize, and maximize buttons fade out with the buttons beside them, and come back as the pointer nears them. They still work while faded.
Fade site title	The site's icon and title in the top-left corner fade out, and come back as the pointer nears them.
Tabs shown	How many tabs the title bar shows: the one you're on, then the ones you used just before it. At 0 it shows none.

Title bar buttons turns each button on or off, in the top left (Browser menu, Home, Back, Forward, Reload) and the top right (Pinned extensions, Make default, Screenshot, History, Downloads, Settings, Plugins, Support, Side chat). Reset to defaults puts them back.

Glow and motion

Context menus sets how brightly your theme's main color glows around right-click menus, down to none.
Button shine puts a soft light on raised buttons. Off, they're a solid color.
Animations: System animates unless your computer asks for reduced motion, Always animates regardless, and Off switches tabs at once and shows panels in place. The same setting is in Settings → Performance.
Scroll long tab titles: hovering a cut-off title in the command center or the title bar scrolls it to the end. At the end of a title picks what happens next.

Profiles and appearance

The shared theme and background belong to your default profile. Any other profile starts with the same look, then keeps its own changes, and Changes apply to doesn't show there. See Profiles.
