Answer 1

File sent as requested.
Couple of notes:
Original set up for three parallax picture boxes.
First box contained picture file that was set at “original size” and was large enough to meet motion requires without reaching end of picture and reach 100% of landscape monitor.  It reached 100% and was acceptable in FF and Chrome.
Second box contained picture file that was set at “original size” and was large at original size and was large enough to meet motion requires without reaching end of picture and but was centered at almost 100% of landscape monitor.   It was centered and acceptable in FF and Chrome.
Third box contained picture file that was set had tile vertical as it wasn’t large enough in certain settings and needed repeating.  It was wide enough to reach 100% of landscape monitor.  It reached 100% and was acceptable in FF and Chrome.
Both FF and Chrome displayed great.  Images 1 and 3 were 100% wide and image 2 was about 90% wide and centered.  Start motion and end motion displayed photos images in exactly the location as desired.
IE11, Images 1 and 3 were 100% width.  Image 2 was still at 90%, but left aligned.  Additionally, all images motion started and ended at a different point than when displayed in FF or Chrome, causing the images to be off of where I would like them to start and end the motion effect.
I was able to correct the left alignment of image 2 by changing it from ”original size” to “tile vertically”.  I subsequently changed all pictures to “tile vertically”
So the remaining issue is that all images motion starts and ends at the wrong point in IE11 vs FF and Chrome.
Lastly, if you look at the site on an iPad, although it wasn’t sized for the smaller screen, it displays very well and the anchor menus work well, with one exception.  The site jumps around when scrolling with touch, and when you touch scroll to the end, it wants to jump you back to the top. If you have time, could you look at this as well.
One bug I did find on all browsers, was that if I put a 100% width block and checked “footer”, it caused the site to add a lower scroll bar at the bottom when previewed. The only way I was able to work around this was to remove the 100% block from the footer.  Feedback on this would also be appreciated.
Thanks
