Now is it possible to call the primaryColor in the st.markdown of the button automatically so that whenever I change the color code in the theme, the button color will change too? In that case, what should I write in the code?
This looks like an automatically generated classname. This will probably break quite fast.
The css selector div.stButton > button:first-child is a bit more robust as the class name stButton is set in the react code. This is of course not a garantee that it won’t break in new streamlit releases as it’s a hack to change the color of a bottom.
You can read the config.toml file with toml python package and insert the color codes into the css string you enter in the markdown object.
I can look the video when the media file is locating on streamlit server machine; if the video is just a link to youtube, I will can not look it.
Maybe you can download the video from youtube and upload it to streamlit website if it is possible.
