"OK, enough examples because CodePen has a homegrown tool of its own called slideVars. All you have to do is import it and call it in the JavaScript panel: import { slideVars } from "@codepen/slidevars"; slideVars.init(); You can import it into a project off CodePen if you're so inclined. That two-liner does a lot of lifting. It auto-detects CSS variables in your CSS and builds the panel for you, absolutely-positioned in the top-right corner:"
"Pretty cool, right? You can manually configure the input type, a value range, a default value, unit type, and yes, a scope that targets the element where the variables are defined. As far as units go, it supports all kinds of CSS numeric units. That includes unit-less values, though the documentation doesn't explicitly say it. Just leave the unit property as an empty string ("")."
"I guess the only thing I'd like is to tell slideVars exactly what increments to use when manually configuring things. For example, unit-less values simply increment in integers, even if you define the default value as a decimal: It works in default mode, however: There's a way to place the slideVars wherever you want by slapping a custom element where you want it in the HTML. It's auto-placed at the bottom of the HTML <body> by default."
slideVars is a CodePen tool that auto-detects CSS variables and generates an editable UI panel when initialized with import and init. The UI appears absolutely positioned in the top-right corner by default but can be placed via a custom element in HTML. Variables declared on :root with default usage are detected automatically; scoped variables require manual configuration. Manual configuration can set input type, ranges, defaults, units (including unit-less by using an empty unit string), and target scope. Unit-less values increment as integers by default, and finer increment control for manual configurations is not exposed.
