More About This Demo From The Author
In this animation, the Vernier scale can be moved along the main scale so that small measurements can be made, correct to 0.1 mm.
It works well with Google Chrome, Safari and Internet Explorer. Unfortunately, not very well with Firefox due to an issue with slider control.
