Perfect timing! I was just looking around for a way to stylize the tooltips beyond the defaults.
This example, and another that you posted a while back Styling the Tooltip Window possible? - #2 by kuligaposten has helped me to not only change the background color on every tooltip on a page (to match the site color scheme), but also how to italicize a portion of the title using the data-bs-html=“true” data attribute.
Great stuff!
Thanks again.
