Cool CodePen Demos (August 4)

idea form

This demo is a cool idea submission/reminder component. The smooth transitions, a perfect choice of colors, and the right amount of interactions make for a nice user experience. This is the first of two demos in this list by Jon Kantner.

A swinging robot

Amit Sheen showcases the 3D power of CSS again. This time it is a robot playing in a swing. Check the details, and how the different body parts move together to create a fluid and beautiful animation.

Bird’s Eye Metropolis

An impressive infinite view of a city from the sky (move the mouse over it to change directions.) And do you know what makes it even more amazing? It doesn’t use any of the popular 3D libraries! It is vanilla JavaScript. Kudos to Niklas Knaack for an incredible demo.

Chandler hugging an album meme generator

Based on a recent political meme (that she also coded), Ines brings a Friends-inspired meme: Chandler Bean holding an album. The sleeve is a file input, so you can personalize the image with whatever you want. Neat.

I heard you like rotations

Another 3D animated demo. A platform(?) floating in space, spinning and rotating non-stop. This hypnotizing demo by Scott R McGann is also coded in vanilla JavaScript and a canvas.

Mood Board

Hannah shared this board that doubles as a nice image gallery for the web. With little animations and transitions, it has a high-school/college vibe to it… Did anyone say nostalgia?

3D spatial scroll zoom

More 3D CSS! (There’s definitely a pattern in this month’s list.) Combining scroll-driven animations with 3D translations and opacity creates this cool effect in pure CSS. It’s a great demo by Adam Argyle.

Rube Goldberg HTML Form

This is a fun idea neatly implemented by Ksenia Kondrashova. As you fill in the form, the contraption moves getting the submit button closer to view. The machine may be impractical, but it makes the form different and brings a wow factor.

Text Message Preview in Badge

Another component by Jon Kantner. This is an interesting way of presenting data: not only do we know there’s a message, but we can read it by hovering over the badge. This could be useful beyond mobile (where the hover effect would be a challenge) and for notifications on the web too.

Carousel

Closing the list with, there’s another 3D CSS demo, this time by Vicio Bonura, who created a CSS carousel that could help as a template to generate other carousels as the code is simple and easy to follow.
