A simple streamlit component that returns the dimensions of the container where it is rendered. This may be used to format other components that require the dimensions of the container.
If multiple st_dimensions components will be used in the app, each component must be given a unique key value. Otherwise, the key argument is not required.
The current version only provides the width of the container in pixels.
pip install streamlit-dimensionsimport streamlit as st
from streamlit_dimensions import st_dimensions
st.set_page_config(layout="wide")
st.title("Main Dimensions")
st.write(st_dimensions(key="main"))
with st.sidebar:
st.title("Sidebar Dimensions")
st.write(st_dimensions(key="sidebar"))
