Hello.
Is there a way to make a button with some embedded image. I tried a superposition but it doesn’t work.
Found it! I just needed to add the same css than used for image widgets.
I found this YT video very helpful. It's a little old so there may be a better way to do it, but what is explained still works.
I used this CSS code and it worked like a charm:
background-image: url('path/to/your/image.jpg');
background-size: cover; /* covers entire button /
background-repeat: no-repeat; / prevents image from repeating */
