Neon Gooey Loader
I experimented with SVG filters and keyframes animations to build a loader with a Googey effect.

See the Pen Error 404 with pure CSS: Monument Valley inspired by Susana Casasola (@SusCasasola) on CodePen.
I created an illustration for an Error 404 page using only CSS properties. I was very inspired by the Monument Valley game, which had a very beautiful art with impossible landscapes. I still use its soundtrack to concentrate while coding.
See the Pen Homeday interactive buttons by Susana Casasola (@SusCasasola) on CodePen.
While working at Homeday I participated on the "Product Engineering Week". Me and my team wanted to experiment with Micro Interactions, so we designed a bunch of buttons, with loading and finished states. Push them! Do not miss the animations.
See the Pen Squared animations by Susana Casasola (@SusCasasola) on CodePen.
Just a bunch of white squares rotating on a black canvas... or are they?
My goal here was to experiment with the CSS animations timing and delays. In order to give the illusion, I would need to update the background at the right time.
See the Pen Dots animation by Susana Casasola (@SusCasasola) on CodePen.
I saw a GIF that was showing this amazing optical illusion where it looks like the dots are rotating but actually they are moving on a straight line. I wanted to recreate it with CSS, so here it is. It was very interesting that a very important part to make it work was the "ease-in-out" timing function, and the delay for each dot.
See the Pen Menu animation with transitions by Susana Casasola (@SusCasasola) on CodePen.
Go ahead and click the menu icon above. The interaction that you see is animated only with CSS transitions, each one delayed a bit to start one after another. It was very interesting for me to test how a bunch of transitions can be chained to create a very different layout.
See the Pen CSS Raindrops by Susana Casasola (@SusCasasola) on CodePen.
This looks like a photograph from a window, right? But guess what, the raindrops are rendered using only CSS. There is a picture indeed, but it's blurred. Each raindrop is a reflect of the same picture, giving a rainy window effect.
