Here’s an updated project that also includes a fix for the mail icon in the Footer. Have fun!
Thank you @tpbradley and @dan for diving into this! I probably wouldn’t have come up with the idea of adapting the custom HTML the way you have solved it now. I lack the time and experience. By the way, I only use the custom HTML because I want to test whether the views are credited to my YouTube account in this way. If I use your video component, the views will probably not be credited to my YouTube account, I assume.
@dan are you sure this belongs here? The content of this link does not look familiar to me.
