What is Moonlight?

Moonlight consists of mostly sunlight (with little earthlight) reflected from the parts of the Moon's surface where the Sun's light strikes. The intensity of moonlight varies greatly depending on the lunar phase, but even the full Moon typically provides only about 0.05–0.1 lux illumination. When a full Moon around perigee (a "supermoon") is viewed around upper culmination from the tropics, the illuminance can reach up to 0.32 lux. The color of moonlight, particularly around full moon, appears bluish to the human eye compared to most artificial light sources due to the Purkinje effect. The Moon's bond albedo is 0.12, meaning only 12% of incident sunlight is reflected from the lunar surface. Moonlight takes approximately 1.26 seconds to reach Earth's surface. Scattered in Earth's atmosphere, moonlight generally increases the brightness of the night sky, reducing contrast between dimmer stars and the background.

Parallax Scrolling Effect

Parallax scrolling is a web design technique in which the website background moves at a slower pace than the foreground. This results in a 3D effect as visitors scroll down the site, adding a sense of depth and creating a more immersive browsing experience. Parallax is based on optical illusion. Since the human eye perceives objects that are close to us as larger than things farther away, we perceive distant objects as if they were moving more slowly. The illusion has been long adopted into parallax across different mediums, fostering a realistic effect. Its first use was in traditional animation, dating back to as early as Disney’s Snow White and the Seven Dwarfs, and in video games such as Super Mario. With advancements in CSS and HTML, parallax effects later evolved into the world of web design as we know it today.
