This is a standard p tag. check out this content, which looks like nothing "triggerable", but if you click it, you'll see the embed. In theory, you can make a huge clickable element, but I would try to keep these smaller and not get too fancy. This is some other content inside of this. This whole thing is a stealth trigger.
If you click this image, you'll see a popup from it
class="cta-modal-trigger" data-template="vacation_investment"
class="cta-modal-trigger" data-template="vacation_properties"
Please keep in mind, you can append this to an existing class. For example, this next link has the class of hl-button, which changes the way it looks, but it still triggers the modal.
