How to customise popups so they match your website's design

By the SeizeLead team · 5 min read · 17 October 2026

Yes, a popup can be customised to match your site, and it should be. A popup that looks like part of your brand earns more trust than one that looks bolted on.

Start with your brand basics

  • Primary and accent colours from your style guide.
  • The same font family as your site.
  • Your corner radius and button style.
  • Your tone of voice in the copy.

Colours

Use your brand accent for the main button and keep the rest neutral. Check that text has strong contrast against its background.

Fonts and sizing

Match your site's font and keep sizes close to your body text. A popup in a different typeface looks like a third-party ad.

Spacing and shape

Copy the rhythm of your site: card padding, border radius and shadows. Consistency makes the popup feel native.

Copy and tone

Write as you do elsewhere on the site. A playful brand can be playful; a formal one should stay formal.

Check every size

Preview on desktop, tablet and phone. Fix text that wraps awkwardly and buttons that sit too close to the edge.
