With Solo, you can upload custom images for your website. Solo does not currently support directly uploading of videos or files. For videos and files, we recommend hosting on YouTube, Vimeo or Google Drive accordingly. You can then configure buttons in Solo to point to links to those videos or files.
Solo also has a Video section to embed a video on your website. Click Sections at the top and add the ‘Video section’ to your website. Scroll to the video section and click ‘Edit.’ You can add a URL to your video to feature on your website.
