Realistic Rainy Window Generator with HTML, CSS, and JavaScript

Realistic Rainy Window Generator with HTML, CSS, and JavaScript

This time, I created a Blogger-ready rainy window generator inspired by a CodePen rainy glass background experiment. The demo recreates the feeling of looking through a wet window by combining a scenic background, animated canvas raindrops, blur, glass overlays, and a small weather-style HUD.

The live demo below is not embedded from CodePen. It is written directly with HTML, CSS, and JavaScript so it can run inside a Blogger post. The original idea focuses on an ambient rainy glass background, while this Blogger version keeps the implementation compact and easier to customize.


Features

  • Direct Blogger implementation without iframe embedding
  • Animated canvas raindrops and falling streaks
  • Moving blurred background presets
  • Adjustable rain intensity and glass blur
  • Weather and clock style HUD
  • Mouse interaction for small splash effects
  • Scoped CSS so it does not affect the Blogger theme
  • Separated HTML, CSS, and JavaScript code boxes with copy buttons

Implementation Notes

The rain effect is rendered on a canvas layer placed above the background image. Each raindrop has its own position, speed, length, and opacity. The background is animated slowly underneath the glass layer to make the scene feel alive.

The interface is scoped inside .rain-window-demo, so the styles and scripts are limited to this post section. This makes it safer to paste into Blogger without changing the rest of the blog layout.

Living Rainy Glass

Canvas raindrops slide across a blurred scene, while the HUD and control panel float above the window like soft glass.

Test Code

Below is the test code used for this Blogger implementation. The HTML, CSS, and JavaScript are separated so they can be copied individually.
