I'm looking to enhance the functionality of the main slider on this particular page. Currently, there are left and right arrows as well as grey and blue boxes underneath that allow users to navigate between four slides (which repeat using only two images). My goal is to incorporate the same functionality into the four box graphics (nextaire, save energy, etc.) so that when a user clicks on one of those graphics, they will be directed to the corresponding slide. Additionally, I would like the blue/grey box below to align with the selected slide. Each graphic also has "on/blue" states similar to what the nextaire graphic currently displays.
This may require some advanced jQuery skills, which I am still working on improving. I was considering exploring possibilities within the functions.js file to achieve this desired outcome.
