Why does this happen?

Why is it that if you display Marquees beneath each other, after 5 minutes they come out of alignment?

I've created an example here:

maybe becuase the time between making the first and second is really small but after a while it starts to get out of sync.

Sort of like the butterfly effect for any philosphers/scientists here.

If you wanna learn about the butterfly effect without being flooded with ads about the movie, google for the "chaos theory"

But yes… as scanky said

I think you could be right however because of the varying effects on the half triangle structure for example: Sometimes if you open the page you get 2 slopes in it going in the same direction, sometimes if you open the page you get 3 slopes in it going in different directions, sometimes if you open the page the whole structure in on one slant, there must be more than one explanation.
