Customising your popup design


Your popup should feel like a natural extension of your store. With the built-in design controls, you can easily match the popup to your brand colours, typography and overall style without needing any code. This guide walks through each section so you can confidently customise the look and feel of your popup.



Where to find Popup design

Access the Popup design in the left-hand menu.

This section controls the main appearance of the popup container.

What you can customise:

  • Background colour: Choose a background colour that complements your store theme.
  • Close icon colour: Adjust the colour of the close button so it stays visible while matching your design.
  • Rounding: Soften the edges of your popup by increasing the rounding.
  • Border toggle: Turn on a border for a more structured look or keep it off for a clean and modern feel.
