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.
Markdown
Display string formatted as Markdown.
st.markdown("Hello **world**!")
Title
Display text in title formatting.
st.title("The app title")
Header

Subheader

Caption

Code block
