Well, I was trying to embed a GIF from Giphy into my website.
I tried to use this one for testing and realised it didn’t work.
<iframe src="https://giphy.com/embed/eoxomXXVL2S0E" width="480" height="360" frameBorder="0" class="giphy-embed" allowFullScreen></iframe><p><a href="https://giphy.com/gifs/internet-eoxomXXVL2S0E">via GIPHY</a></p>
The reason I didn’t want to use video was because I would prefer not to download each and every video file I wanted to add. In the long run, that seems like it would just slow down my website, so I omitted it.
Plus, this isn’t just about a video file. It’s any embed link that I have tried using in an HTML block. None of them seem to work and just show error 404.
