As a Web Designer, I also specialize in creating Wedding Websites for weddings, civil unions, and other events.
Here's an example of a website with a fresh and minimal design that provides guests with all the information they need to know to attend the event. The sections include details about the date, timings, location, and directions on how to get there. Additionally, there's a form for guests to confirm their attendance and guidance on gifts.
The entire concept is designed to make invitations more essential and functional, minimizing the amount of paper used for announcements. This way, invitations can focus on including only the most crucial information.
