I am teaching my students how to use Wix Website Builder for their portfolio. Pixabay is an excellent site to use for my students to have content on their website that shows what they are going to learn. Once they create their own content they can replace the Pixabay content, or they can leave it as long as they create a link back to the Pixabay site and the artist that created the media.
My website is still under construction, so I just posted a screenshot. I used an image on a camera to put in the background and a video that uses a double exposure effect to show people and animated effects.
