Here lies a collection of little web-based tools I've made for various purposes.
nth-child Selector Tester
Try out different nth-child options against a list. Handy for reminding yourself what the CSS is for highlighting every 3rd item.
This is just a page that shows you your webcam. Basically a mirror. Handy for checking yourself out before jumping on a Zoom/Team/Slack/Meet/Skype/Blah/Blah/Blah call. Inspired by my wife's work laptop which doesn't have the Camera app installed and locked down so she can't install it herself.
Copy-paste stuff into a textbox and it'll automatically appear sorted on the right. Stupidly simple, occasionally useful.
