I would like my document as I am writing it to be independent of software layouts as I think it would be a better decision to make at the end of the process. What would be good ways to denote stylistic notes within the text for later use. For example say I wanted to publish this text you are reading and I wanted for there to be a quick tip box on the right margin of the page. How would I denote this, something like this:
Quick Tip Box "This is my Quick Tip Box"
What are some different ways to achieve this during the initial stages of writing.
