New informative / notification component

I did not like the st.spinner, due to its always being depended on the position of the div.
So i’m working on a new component which will make a better version (IMHO) of that.

the notification inherits the theme color.
the notification is sticky on top, and moves with the navbar.

currently i’ts super raw.

This is something we were discussing just the other day as a potential addition to the official API :smiley:


Hey @BugzTheBunny!

That’s wonderful! I’m going to add this to our components tracker under the “under development” section!

Happy Streamlit-ing!


Woah! That’s a great component @BugzTheBunny! :clap:

Very nice! I do like this more than the spinner, will definitely start using this. Also, not sure if it was intentional, when I run this with a light theme or anything not using a black background colour, the notification background seems to be using a fixed colour.

in the file

background-color: #0E1117

I added the bc variable in from your style dict and everything worked as expected.

background-color: {styles["bc"]}

Keep up the great work!


Indeed, I left some things there like that for my needes, but i made it as much as modular as i could for that point :slight_smile:

In my personal code i’ve made it a bit less flex and more depended, in this version i shared, its more modular, so i didin’t notice all of the details when refactoring it :smiley:

Thanks for noting it!
