Maybe I’m just missing something in the BSS program, but is there an option to wrap text around an image? Specifically, I want to place an image in the upper left corner of a paragraph and have the text wrap around it with some padding. Didn’t see anything about this in the tutorials.
There are multiple ways to add attributes. There's an Options pane, with the Look & Feel tab, the Styles pane, you can manually add standard bootstrap 4 class names. It all depends on how well you know bootstrap vs. how you just know BSS.
But if you don't know what a float is, how the flexbox works, how to layout using columns or the basis of responsive design etc. you'll never do a good job.
My suggestion is to learn bootstrap before using this software. There are many great courses and tutorials, same even free from edx.
