I have tried doing this by trying to select the writing I want enlarged and colour changed, but for the life of me every time I try I end up turning most page the same style.
I am sure I am missing a simple trick here but please someone put my mind at rest.

Thank you!

Hey Bryan.
1- Put quotes around the words you want to show as quote.
2- Highlight those words, quotes included.
3- Click button in the editor with the big black quotation marks.
Go preview changes and it should be good.
If it don't work, let me know and we'll get you some more help.
