I want text to pop up when the cursor hovers over specific words

Site URL: https://www.stenstromconsulting.com/

Hello, on my homepage our founder has these keywords that she believes are the fundamentals of our business. Currently when you click on them it links to another page to expand on the thought. I would like for someone to over their cursor over the word and the quote pop up. Any help is appreciated. Thanks
