How to recreate this mouseover effect from Blue Origin? : <p>On <a href="https://www.blueorigin.com/" rel="nofollow">https://www.blueorigin.com/</a> they have a mouseover effect on the front page with the "Astronaut Experience" and "tech..." boxes that are side by side each other underneath the video.</p>

<p>I am learning how to code websites right now, and working on making one right now with that similar style of effect. How would I be able to implement this? I have some basic javascript knowledge, html, css and using nodejs+express</p>
