Rain effect on pages

Written by @kerixa 21 August 2012

Beautiful and dynamic background effects will attract the attention of website visitors. In the following code, we have one of these effects that have a special beauty, especially in websites with dark backgrounds. This effect simulates rain and also has 3 buttons to adjust the rainfall model. For example, it has the possibility of single-drop rain and heavy rain. Enjoy!
