This is a custom Angular 8 demo element. See my website page for more.
Currently, the custom element file is about 230 KB. The file should become even lighter using the Ivy engine (scheduled for Angular 9).
Type a short text and see the resulting abacus. Additionally, you can change the start and end color for the background gradient.
Note that not all the browsers yet support this custom element. Please use a modern browser (ES6).
