With the use of coding skill like
HTML (Hypertext Markup Language),
CSS (Cascading Style Sheets) you can do anything on your browser.
This is another kind of new way to express the power of coding. Here you can learn how to make “Snow Falling Effect”.
You just copy and paste into your code editor software and run it on your browser. You Don’t need to write manually it again. Just Copy & Paste.
If you don’t understand clearly so you can watch a youtube video which mentions the end of the page.
