In the Sandbox, you can create anything you want or add anything you want with the live composer. With this post, this will allow you to start seeing things in the sandbox or allow you to play around with the different options in Gutenberg to create a post. As you can see from the title and this paragraph, we just have two very basic document elements in use.
And as you can see here, I’ve added an image, but have it on a “right justify” so that any text elements will wrap around it. I’ve also changed the picture to be 50% of it’s original size so that the text does actually wrap around it. Alternatively, you can have it as a “left justify” and the text will wrap around the picture on the right side or you can have the pictured centered with no text wrapping.
