How to position an element at any x / y coordinate?

Given X and Y coordinates, I want to position an element so it’s in that position on screen/window. I want scroll to work as normal, so position fixed isn’t a solution. I want what fixed does but the element should move like a normal element when scrolling.

How to normalize an X and y coordinate?

To normalize this into a unit vector you first must find the length (aka magnitude) of the vector using the equation sqrt ( (x * x) + (y * y)) Once you’ve found the length you can convert it to a unit vector by dividing the x and y values by the length. Multiply this unit vector by your speed and you should be properly moving towards your target.

Which is the numerator of the X and y coordinate?

Essentially, the numerator (top number) is going to be velocity you apply on the Y axis and the denominator (bottom number) is going to be the velocity you apply to the X axis. These numbers already have a bit of a bias on speed though and could improperly influence how fast you end up moving.
