This is a quick example showing how to give an input field “memory”. After you type something once and hit return it will be stored in `localStorage`. String values are ranked based on how often they are selected/entered. I know people don’t like jQuery these days, seems this pen is from a time when I still used it.
There’s definitely room for improvement here - but the key features are covered.
Usually if you want to draw lines in HTML you use canvas or SVG. Awhile back I wondered how I might do it without those. This is really just a proof of concept speed coded answer to that question:
This works by using a div with a border, rotating it and scaling it as needed so it fits between two arbitrary points.
This could be abstracted a bit more, but it works pretty well. I usually choose `setInterval` over `requestAnimationFrame` when prototyping - because I like to easily be able to change the speed of
framebased things like this. If I were to try and make this code more dynamic, I would probably switch out to `requestAnimationFrame`.
If you try and connect two lines together - you’ll notice some inaccuracy - a good argument for using SVG or canvas over something like this. That said, if you are connecting two elements using a single line, this inaccuracy would become irrelevant.
Choose two colors to breed them and create 5 new colors:
This is a speed coded pen from awhile back - the features object is interesting - it allows two objects to be bred together. In this case two colors. I could see this is as part of some advanced/abstract colorpicker that allows the user to home in on a color.
If you look into creating SVG dynamically with JavaScript you might stumble upon `document.createElementNS`. In most simple cases, you don’t need to go down that path. Contemporary libraries handle this stuff internally now (they didn’t always) or if you’re going vanilla… you can integrate this kind of thing somewhere:
