{"version":"1.0","type":"rich","title":"WebCOLD 04","description":"WebCOLD 04 demonstrates interactive font-size control using a custom HTML element called `superSlider`. Two sliders adjust the title and subtitle font sizes of a preview block in real time, displaying the current value in a readout. The custom element, defined via `customElements.define`, wires up range inputs to update CSS `font-size` properties and includes reset buttons. The example uses no external libraries, relying on native DOM APIs like `querySelector` and `MouseEvent`.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-149c63b23e7777b43e04fca62491334a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
