CSS snowflakes for your website, no JS needed!! Working in modern browsers using CSS animation (IE10+).
Just add the code from snippet.html to your webpage and enjoy beautiful falling snowflakes. Snowflakes should not be visible in older browsers, thus not breaking layout.
Tip: You can change color, text-shadow, font-family and font-size at the beginning of the snippet.
Tip2: You can switch snowflakes off with :
.snowflakes { display: none; }
