Question

I have two (or 3) coordinates.

They are the 2 upper coordinates: left and right

How do I create a div where the left corner has the coordinate of the left one and the right corner the coordinate of the right one.

The rotation should be created from these coordinates or this height difference between these 2 points

How can I achieve this?

Answer 1

To get the angle between the two coordinates, you could use Math.atan2

var angle = Math.atan2(Y2 - Y1, X2 - X1);

you could then use a CSS3 property to set the correct angle on the div.
