Hi @alex180500 , I don’t think there is a current way to change the font size for those components. However, you could create something with the html component (Components API - Streamlit Docs). I don’t think we currently support that right now. However, you can try creating an enhancement on the issues page (Issues · streamlit/streamlit · GitHub) and try to get people to react / comment as we do use those to prioritize certain things.
Here’s a way to change exactly those three widgets label sizes (and color, just to emphasize). Of course, colors are dubious and I don’t recommend keeping them
Changing the font-size of text input doesn’t work anymore in the latest versions of Streamlit. Do you have any advice on how to achieve this? I use streamlit 1.20.0. Thanks a lot in advance ^^
