To link up an entire section or div, add the code below to your div tag and replace the # with desired URL
onclick="window.location.href='#';" style="cursor: pointer"
Here is an example of how the final code should look:
<div onclick="window.location.href='/contact';" style="cursor: pointer"> <h1>Heading of the section</h1> <p>More descriptive text</p> </div>
