How to add a wrapper to "text and image" items in Version 7

Hi,

I am working on a Version 7 site and I am a new kid on the block.  I am more of a code editor, than a developer.  I want to make some CSS changes but I am finding the my lack of understanding the format really irritating.

I can create a text block element, and drop an image onto it.  I want to target the whole thing so I can put background styles on it, style the text (so it can be used as a module across the site).

But I can't see how to target the whole thing. The is a blockyui for the text, and a blockyui for the image, they are not nested (prob injected), there are classes, but I can't seem to target the whole block.

I don't know what to do on this one. Can someone help please?

Thanks

I have answered this myself - I have realized without knowing enough about how Squarespace works, I had gone down a rabbit hole.  What I need is Index pages to break up my content.  

Hopefully I'll ask a more rich question next time!

You can target block-id or page id (contain more blocks) or section id (SS 7.1) or index section id (SS 7.0) or...
