One-Shot Any Web App with Gradio's gr.HTML

Gradio 6's gr.HTML now supports custom templates, scoped CSS, and JavaScript interactivity, enabling full-stack web app development in a single Python file.

• •gr.HTML accepts html_template, css_template, and js_on_load parameters to build fully interactive components
• •${value} injects Python state into HTML, props.value updates state from JavaScript, and trigger('change') syncs back to Python
• •Custom reusable components can be created by subclassing gr.HTML, making them work like built-in Gradio components
• •Example apps include a Pomodoro timer with CSS animation, a GitHub heatmap, a Kanban board with native HTML5 drag-and-drop, and ML detection viewers for bounding boxes and segmentation masks
• •Apps deploy to Hugging Face Spaces via gradio deploy or share a temporary link with demo.launch(share=True)
