Image banner

Image 1 (Desktop)

The primary banner image shown on desktop. Recommended: 2000 × 600 px.

Image 2 (Desktop)

Adding a 2nd image enables crossfade animation. Optional second image. When set, the banner alternates between Image 1 and Image 2 with a smooth crossfade. Useful for showing two product views or a before/after.

Image 1 (Mobile)

Recommended: 1000×300 px. Mobile-specific version of Image 1. If empty, the desktop image is used and cropped to fit.

Image 2 (Mobile)

Recommended: 1000×300 px. Mobile-specific version of Image 2.

Video for image 2

Opens in a modal on click. Optional video for Image 2.

Banner link URL

Used when no video is set (single image only). Makes the entire banner clickable, navigating to this URL. Ignored when videos are attached (clicking opens the video modal instead).

Frequently asked questions

How do I trigger the crossfade animation?

Upload a second image in Image 2 (Desktop). The crossfade activates automatically when both Image 1 and Image 2 are set. Adjust the cycle duration with Image transition speed.

What happens if I set both a Banner link and a Video?

The video takes priority. Clicking the banner opens the video modal regardless of the Banner link URL. To use the Banner link, leave both Video fields empty.

Why does my mobile image look stretched?

Always upload a dedicated mobile image. The desktop image (typically wide) gets cropped to fit narrow mobile widths and can look distorted. Use the recommended 1000 × 300 px for mobile.

Can I have separate videos for desktop and mobile?

The Video for image 1 / Video for image 2 fields use the same video for both desktop and mobile. To serve different videos, you'd need a custom development. For most uses one video works fine — modal player adapts to screen size.

Why is my heading too big?

Lower the Heading style from H1 to H2 or H3. The default H1 is intentionally large for hero banners. For promotional strips, H3 or H4 fits better in the smaller height.
