To fill stripe patterns

Hi, I am using Leaflet Plugin very usefully. Thank you for providing such a great plugin. I have one question. I want to fill my geojson file with stripe pattern. I found a leaflet plugin that seems to have this function. Here is the address.

However, since I do not know coding at all, I am not sure how to apply this to Short Code. How can I use this plugin? Or can you make it easy to use Short Code?

Thank you.
