4.gridster usage instructions

The gridster plug-in works normally in Chrome and Firefox, and the special effects display page works normally. However, it displays normally in IE8, but the drag effects cannot be displayed.

Now you can open it to see the drag effect, Oh, it’s so embarrassing! You will also find that it is not smooth. This may be a small bug or imperfection in Girdster. How to improve it, I will talk about it tomorrow!
