How to Add Sparkle Trailing Animation for Cursor

Hi there!
I am sooooo excited because I've finally, FINALLY, after a long long time, found the code for the sparkles that trail after the cursor. I've seen it before in a random blog, and I've tried to find it everywhere but to no avail. Now I found it! And it's simply beautiful.

This is perfect!

Those of you who know how great it is to finally find something after a long while know how I'm feeling right now. Haha.
So! I'm now going to share with you guys the code for the sparkles as seen here.





Okay, for those who don't know how to install this code, please read THIS POST. It's a post about how to install the bubble animation, which is practically the same thing as this sparkles animation, only different pattern. Please follow all the steps given there on how to install the animation, by using the sparkles code instead of the bubble one. The steps are identical, don't worry, kay?

Erhmm..here's the magic code for the sparkles animation (in watermelon red highlight). Please copy this code first.

The part highlighted green is where you can change the colour of the sparkles, while the part highlighted blue is the number of sparkles that will appear at a time.

For the full tutorial on how to install the code, once again, click HERE. Follow the steps, replacing the bubble code with this code above, and you'll be fine.

Happy using! =D
