Hide none after HTML


Hi guys, I am new to streamlit and I tried searching for previous post but didn’t found anything similar yet. Beacuse I am trying to using Tailwindcss through streamlit_tailwind. But after st.write it will have a green text saying none below my html section. Thanks in advance if anyone knows how to remove it.

Steps to reproduce

Code snippet:

add code here

import streamlit as st
from streamlit_tailwind import st_tw
from st_paywall import add_auth
import streamlit.components.v1 as hero
from st_pages import show_pages_from_config, hide_pages

page_title=“Multipage App”,

page_bg_img =“”"

[data-testid="stAppViewContainer"] { background: linear-gradient(to left top, rgb(249, 168, 212), rgb(216, 180, 254), rgb(129, 140, 248)) } #mainMenue {visibility: hidden;} footer {visibility: hidden;} #header {visibility: hidden;}


st.markdown(page_bg_img, unsafe_allow_html=True)


value = st_tw(

If applicable, please provide the steps we should take to reproduce the error or specified behavior.

Expected behavior:
According to websearch if I use placeholder=st.empty(), then write the value to the placeholder should solve the issue. However nothing changed.

Hello! Welcome to the forum! In the future, when you post code snippets, could you please make sure they are formatted as a code block so that they are easier to use?

The short answer is that, if that component works, you don’t need to do st.write(value) at all – the component shouldn’t actually return a value.

In this case, I would recommend simply using a tailwind script with streamlit’s html component, rather than a bidrectional component like streamlit-tailwind:

from streamlit.components.v1 import html

md = """
<script src="https://cdn.tailwindcss.com"></script>

<div class="bg-blue-500 text-white p-4">Hello, world!</div>

html(md, height=600)

Thanks a lot. And apologise for the inconvinence, I didn’t know there’s a way to preview the post.
