Components are the building blocks for your app's user interface (UI). They are the visual elements that make up your app, like buttons, text, and images.

Components are made up of children and props.

Let's take a look at the rx.text component.

Here "Hello World!" is the child text to display, while color and font_size are props that modify the appearance of the text.

Now let's take a look at a more complex component, which has other components nested inside it. The rx.vstack component is a container that arranges its children vertically.

Some props are specific to a component. For example, the header and content props of the rx.accordion.item component show the heading and accordion content details of the accordion respectively.

Styling props like color are shared across many components.

Reflex apps are organized into pages. Pages link a specific URL route to a component.

You can create a page by defining a function that returns a component. By default, the function name will be used as the path, but you can also specify a path explicitly.

In this example we add a page called index at the root route. If you reflex run the app, you will see the index page at http://localhost:3000. Similarly, the about page will be available at http://localhost:3000/about.
