Hey! So glad to see you here. This is the code to create the exact app from Streamlit's Theming tutorial.
Here we have a standard looking streamlit app project, with a README.md file, a
streamlit app python file (Theme_app.py) and a directory that holds a pickled
data file (dataframe.pkl). To take the app and create a custom theme, the only new
aspect to this fairly standard looking project is the hidden .streamlit/
directory which has the config.toml file. It is this file that outlines the
custom theme for this app, which is also the default theme!
