Can you help me create a unique lighting effect for a specific section of my webpage? I'm curious about the techniques needed to achieve a similar effect as seen on another webpage.
Is it feasible to create this effect using only CSS and HTML, or are there other tools or methods I should be aware of?
To create a visually appealing animation of light moving horizontally across the page, you can utilize two background images. One image will serve as the fully illuminated scene, while the other will act as a black shadow with alpha transparency to allow the lit image to shine through.
Begin by setting the full lit image as the background-image: for the <html> element, and assign the shadow image as the background-image: for the <body> tag.
For animation effects, adjust the background-image-position of the shadow image. For added visual interest, consider implementing a Parallax effect using tools like jParallax (http://stephband.info/jparallax/). This technique involves moving the "full lit" image in conjunction with the shadow image movement to create an engaging and dynamic display.
It's possible to create a 'light' effect with CSS3/HTML5 using gradients that transition from black to opaque black, overlaid on top of a fully illuminated photo. This approach might give the appearance of a dynamic lighting effect without actually changing the image itself.
If your goal is to have the image appear to be dynamically lit up, creating a transparent PNG in Illustrator and positioning it above your images with CSS absolute positioning could achieve this effect seamlessly.
