title: How to make a back-to-top button using CSS and HTML only?
body: <p>I'm trying to do a <code>back to top</code> button but to scroll down and up to a certain point on the page. For instance you have a long text and you want to bring the user to the next paragraph by simply having them to click on a link... I've done it in the past but I can't remember how I did it for the life of me...</p>
