Shout-out to <a href="https://twitter.com/RockStarwind/status/1284322826258915328">@RockStarwind</a> for the idea to use checkboxes as an exploratory source for Space Toggle variables. I've been up all night building this as a result! :3<br>
<br>
<br>
Check out the source code here: <a href="https://github.com/propjockey/bcd7sdd">https://github.com/propjockey/bcd7sdd</a> and tweet at me if you want to ask questions or chat! <a href="https://twitter.com/James0x57">@James0x57</a>

<h2>Space Toggle</h2>
<p style="font-family: sans-serif; line-height: 1.5rem;">
This state machine is built in CSS with a trick called "Space Toggle" discovered to kick off the development of <a href="http://augmented-ui.com/">augmented-ui</a> v2 in April 2020. (though unknown to me, it was previously discovered by <a href="https://twitter.com/anatudor">@anatudor</a> about 3 years ago, so credit where due!) You can read more about Space Toggle in these tweets which contain links to JSBins you can explore further with:<br>
<a href="https://twitter.com/James0x57/status/1283596399196680192">Second Tweet, a simple demo</a><br>
<a href="https://twitter.com/James0x57/status/1282303255826046977">First Tweet, an advanced demo</a><br>
Or checkout how Space Toggle is used to make responsive, vanilla, CSS much easier in <a href="https://propjockey.github.io/css-media-vars/">css-media-vars</a> for some more real-world example useage!<br>
