One way to visually highlight one (or several) activities on your website is by adding a highlight to the activity. The steps to set it up are as follows:

1. Log in to your backoffice account and, from the side menu, click Catalog › Activities.
2. Enter the activity you want to highlight by clicking on its title.
3. In the Details tab, choose the language in which you are going to write the highlight in the Activity contents section.
4. Scroll down to the Web customization section and fill in the List highlight with the text of your choice.
5. Click Save.

The highlight will appear in the color that you have configured as secondary color in your website or webplugin.
