Text on a website, if you want it to be, can be a flow of flowery information. A hymn of meanings dedicated to the subject at hand. But it comes down to that first condition; ‘If you want it to be’.
When talking about flowing text we are talking about a kind of writing, a way of talking about something which has a rhythm to it. The difference between logical informative writing and more creative, excessive writing.
To really make the most out of the flowing of text you need to want your text to be that way. Adding flowing flowery text to a website is an extra addition to a normal way of adding text. It can be easy to write about something logically. But to write about it in a way which flows and adds something to the content, simply through its construction is an entirely different thing.
