You can add a background image or video to any section of your website. Upload your own media or choose from thousands of stock photos directly in the B12 Editor.

Changing your website background

1. On the left sidebar menu, go to website Website > pages Pages. 

2. Select the page, then choose the section where you want to change the background. You can do this by clicking the section in the preview or selecting the section name in the left sidebar.

3. In the Background media field, click Replace (just below the small preview of your current background).

To remove your background entirely, click the ⓧ in the top-right corner of the preview.

4. From the Library, scroll through your existing media, select the image or video you want, then click Continue.

To use an image or video you own

​Note: Videos have a small camera icon in the lower right corner.

To generate an image using AI Assist

    • Type a short image description, then select the type and style you prefer.

Background Media Tips:

  • Keep it simple: Images/videos that are not busy (fewer details and colors, less contrast, etc.) work best as backgrounds—making sure your text is legible and easy to read.

  • Consider screen size: Choose an image that will look good on multiple screen sizes. On desktop screens, your image may be shown in landscape orientation, while on mobile screens, your image will likely be shown in portrait orientation. Thus, if the focus of your image is toward the center of the frame, it will look great on both mobile and desktop screens!
  • Ditch the text: We don't recommend adding background images with text on them. For SEO reasons and to make sure your site is fully responsive and accessible, all text should be added to the appropriate text field in your section.
