Background colour

A Dark theme inverts the page for comfortable reading in low light. Toggle it in Display options or via the system appearance setting.

Zoom

Scroll with two fingers while holding ⌘ (Mac) or Ctrl (Windows) to zoom, or use the zoom controls in the toolbar. Press ⌘ 0 / Ctrl 0 to fit the page width.

Fit to width vs. fit to page

• Fit width — the page fills the screen edge-to-edge horizontally. This is the default and gives the most readable text size.
• Fit page — the entire page is visible at once, useful for checking layout.
