How this works

The navbar uses CSS Flexbox with two child panels. The left panel has a dark background and contains the logo; the right panel has a light/white background and contains the links and CTA. A clip or border on the join creates the hard-edge split. No pseudo-elements or images are required — the two-tone effect is purely background colours on sibling divs inside a flex row.

Make it yours

  • Change the split ratio by adjusting flex: 0 0 260px on the left panel — a wider logo panel works for longer brand names.
  • Add a diagonal cut at the split by using clip-path: polygon() on the left panel for a more dynamic editorial feel.
  • Invert the colour scheme — light left, dark right — for a completely different brand personality.

Gotchas — read before shipping

  • On mobile, the two-panel layout typically stacks or collapses into a single-colour bar — ensure the mobile state is designed separately.
  • If you use a diagonal clip-path on the split, the right panel content needs left padding to clear the overlap.

Browser support

clip-path polygon is well supported in modern browsers; provide a straight-edge fallback for IE11.
