Change color of text within ONE block of text

This is what I'm seeing:

Which spacing are you referring to here?

Just a note that all of these issues could've been avoided if you use GenerateBlocks as David suggested initially.

See screen print attached below...

Then add small-spacing to that column like you did for the next two:

Well... it looks like I have added it... but like I said, it is VERY difficult to make the first column selected for certain.
See image attached...

You can quit on me Leo. Sounds like you're a tad exasperated with helping me, and I get it. But GP Blocks did that to me.

Try using the List View to select the correct element:

Done... but it made no difference... see attached image below...

It's still not there from what I can see.

Did you clear the caching plugin after adding it in?

Yes I did, and I've double-checked and it is correctly added to the column NOT the paragraph.
Cache has been deleted too.

Now it's there.

You have not added small-spacing to this paragraph:

Please see the video below this...

You need to add small-spacing here:

Done... soooo... what I don't understand is the other two paragraph blocks DON'T have that code added ONLY to their columns... yet... the first one needed that class added to BOTH the column AND the paragraph block.

Boy! Now I see why soooo many long time users are leaving WordPress for better a CMS.

THANK YOU Leo!

You are welcome.
