I did it! DIY link button! But... I can't post it... I would be grateful if someone could tell me why... Yesterday kittens and today video with our dogs

Hello my dear friends!
I spent all day today learning the secrets of creating a link button. This task turned out to be quite difficult for me. At some point, I really despaired that I wanted to enroll in a programming school!😁
I've been wanting to do this for a long time because I need proper links to my Etsy shop and my shelter's YouTube channel. Now is a difficult time and I am trying to develop these two areas more actively. I tried once, but my link button didn't work and I gave up trying. But this time I decided not to give up.
But still, I have to admit that modern programming methods are so far advanced compared to what they were in my youth that I feel like a caveman ...
And so, when I tried to make a post... it didn't work for me... The program demanded to remove the html "button"... Can someone tell me why? 🤔

The kittens who arrived yesterday are doing well. They are, of course, completely wild and unsocialized. But they are still very small, so I believe that we can fix it.
