Help! How to make text that changes into a separate block of text when clicked upon?

Hi! I’m working on a poetry project on Wix that showcases an interactive experience with poetry. My vision is for the themes of the poems to be floating around the page (i.e. sentience, death, consciousness, etc.) and for the poem(s) to appear when the text is clicked by the user. That way the reader can choose what poems to engage with based on which themes speak to them. Any idea how to do this? Thanks!
