import gradio as gr with gr.Blocks() as demo: with gr.Group(): gr.HTML(value="<p style='margin-top: 1rem, margin-bottom: 1rem'>This <em>example</em> was <strong>written</strong> in <a href='' _target='blank'>HTML</a> </p>") demo.launch()


Creates a component to display arbitrary HTML output. As this component does not accept user input, it is rarely used as an input component.


As input component: (Rarely used) passes the HTML as a str.

Your function should accept one of these types:
def predict(
	value: str | None

As output component: Expects a str consisting of valid HTML.

Your function should return one of these types:
def predict(ยทยทยท) -> str | None
	return value




Class Interface String Shortcut Initialization



Uses default values


import gradio as gr demo = gr.Blocks() with demo: inp = gr.Textbox(placeholder="Enter text.") scroll_btn = gr.Button("Scroll") no_scroll_btn = gr.Button("No Scroll") big_block = gr.HTML(""" <div style='height: 800px; width: 100px; background-color: pink;'></div> """) out = gr.Textbox() x: x, inputs=inp, outputs=out, scroll_to_output=True) x: x, inputs=inp, outputs=out) if __name__ == "__main__": demo.launch()

Event Listeners


Event listeners allow you to respond to user interactions with the UI components you've defined in a Gradio Blocks app. When a user interacts with an element, such as changing a slider value or uploading an image, a function is called.

Supported Event Listeners

The HTML component supports the following event listeners. Each event listener takes the same parameters, which are listed in the Event Parameters table below.

Listener Description

HTML.change(fn, ยทยทยท)

Triggered when the value of the HTML changes either because of user input (e.g. a user types in a textbox) OR because of a function update (e.g. an image receives a value from the output of an event trigger). See .input() for a listener that is only triggered by user input.
