Changing the code to move the elements in opposite directions is my goal. I attempted multiplying the second element by -1, but unfortunately, I keep ending up with a NAN or undefined result. Any suggestions on how to achieve the desired effect?

To retrieve the transformation matrix, you can use the following code:
var el = document.getElementById("element2");
var st = window.getComputedStyle(el, null);
var tr = st.getPropertyValue("transform");
The tr variable should contain a string similar to this (assuming a 2D transform):
matrix(0.8660254037844387, 0.49999999999999994, -0.49999999999999994, 0.8660254037844387, 0, 0)
Next, extract the 6 values from the matrix, perform the necessary inverse operations, and set the new transform for element1 using:
document.getElementById("element1").style.transform = matrix(a, b, c, d, e, f)
You can refer to this source for further information: https://css-tricks.com/get-value-of-css-rotation-through-javascript/
If you have defined the transform for element2 yourself, it might be simpler to invert that input and apply it directly to element1 instead of trying to recover it from element2.
