Themes¶

Built-in st_yled themes let you apply a complete visual style from st_yled.init(...).

Don't forget to run st_yled.init(...) on each of your app pages.

Quick Example¶

import st_yled

# Apply a built-in theme template
st_yled.init(theme="bauhaus")

# Disable light and dark mode selection for the user -
# serve only the "default" for a theme
st_yled.init(theme="bauhaus", disable_light_dark_mode = True)

When a theme template is selected, st_yled updates the Streamlit theme sections in .streamlit/config.toml.

Available Themes¶

• Bauhaus
• Luxury Fintec
• Newspaper
• Playful Startup
• Scandinavian

How It Works¶

• st_yled loads theme definitions from src/st_yled/themes/*.json
• The selected template is translated into Streamlit theme keys
• Theme values are written into .streamlit/config.toml
• Light and dark mode are supported by each template
