thanks for your reply. I downloaded the particle files and now everything is working. I have a small problem with the custom marker
icon. I use a png image which is square (30px x 30 px) but the particle makes it rectangular. Inspecting the css with Chrome I was able to apply this rule:
transform: translate3d(168px, 200px, 0px);
this way the image is displayed correctly in square size, but as soon as I reload the page the changes are lost. Where can I set up a custom.scss file to write the above code?
Thanks for your repky
