With Higher Logic Vanilla's (Vanilla) Foundation theme, you can specify different responsive breakpoints to control how the theme banner and content banner images in your community display on various devices.
Desktops, tablets, and mobile devices have different screen sizes, so it's important that your images adapt to look as good as possible on each type of device. To ensure a clean look, you can upload different-sized images for when your banners display on desktops, tablets, and mobile devices.
✔️ TIP: See Image notes, below, for image-file types and Vanilla's size recommendations.
Enable Responsive Breakpoints
There are two toggles in the Theme Editor that can be enabled to accommodate different-sized images for each device type.
You can enable responsive breakpoints for the Banner and Content Banner:
- The Banner displays on various pages of your Vanilla community, such as Categories, My Bookmarks, My Discussions, and Recent Discussions.
- The Content Banner (which is optional) displays on pages that contain content, such as community posts (including discussions, ideas, questions, polls, events) and knowledge base articles.
- To access, click Content Banner from the Styles menu.
- To learn about this banner, see Content Banner.
When you enable the option for these two banners, the panels expands to display two fields: Mobile and Tablet.
Choose banner images
The steps for selecting mobile and/or tablet images is the same for both banners.
✔️ TIP: See Image notes, below, for information on preparing your images.
To choose images for the banners:
- Click Choose Image to navigate to and choose an image for that device type. The image displays as the banner in the "design canvas" and in the ellipsis field.
- Click the ellipsis and choose Revert to re-apply the previous selection or click Delete to remove the image, leaving no image.
