How to Customize the Branding for your Virtual Event in Zuddl

2 mins read

Zuddl lets you customize the branding for your event with different themes and color choices by adding graphic elements like background images and logos. You can also see your settings applied in the event preview for both desktop and mobile versions.

Branding menu page

The branding setup is divided into three sections:

  • Theme
  • Navbar
  • Virtual Background


Choose a color theme from the two options - Custom (selected by default) or Dark. These colors are applied across the live event on all venues and sub-sections.

Apply custom colors

To customize your theme by choosing colors:

  1. Choose a Primary color from the color picker or copy and paste the color hex code. This color is used for all primary actions and highlight sections.
  2. Choose a Secondary color. This color displays any text on top of the primary color. The secondary color is visible only for the Dark theme.

Our system automatically picks a Secondary color for a Custom theme that complements your chosen Primary color.

Add a background image.

A background image is applied in the event behind venue elements and panels. You can apply different background images for specific areas like rooms or booths, but the image uploaded here will be used as a default background in all other venues.

  1. Click Edit Background button.

    Edit background image

  2. From the sidebar, choose an image from the available templates or Upload your own image with a recommended size of 1920x1080 pixels in a JPG, JPEG, PNG, or GIF file.

The upper navigation bar (Navbar) for the event shows the different venues and can be customized for branding:

  1. Upload an Event Logo with a minimum size of 200x80 pixels in a JPG, JPEG, PNG, or GIF file up to 4 MB. The event logo is visible on the left of the Navbar. You can drag or drop an image or click on the Browse button to upload an image for the event logo.
  2. Select the colors for the Navbar:
    1. Choose a Navbar color. This is applied to the background of the Navbar.
    2. Choose a Navbar text color. The text labels on the Navbar will use this color.
    3. Choose a Selected tab color. This is used to highlight the currently selected venue tab.
