Welcome to the Q&A Forum

Hi - we are a website that sells tours. We have category pages that list the tours in that category (by city, by length of time, theme, etc). At the top of each category page, before the buttons linking to the tours, there is a category description. It is a pretty long paragraph. We are redesigning the website and think it would look nicer to show 2-3 lines of text and then have a down arrow and 'read' more so people can click and it would expand to show the full category description if they want to read it and it won't take up so much room that way. My question is - will this affect SEA at all? Or because the text is still there, just hidden, it won't do anything? Our site ranks very high in organic searches on google and we do not want to do anything that will hurt SEO. thanks.
