Text elements
Streamlit apps usually start with a call to st.title to set the
app's title. After that, there are 2 heading levels you can use:
st.header and st.subheader.
Pure text is entered with st.text, and Markdown with
st.markdown.
We also offer a "swiss-army knife" command called st.write, which accepts
multiple arguments, and multiple data types. And as described above, you can
also use magic commands in place of st.write.
