Create 2 different buttons with different styles

button_style = “”"

.stButton > button {
color: white;
background: green;
width: 100px;
height: 50px;

st.markdown(button_style, unsafe_allow_html=True)

But this will change all button styles, is there any method?
by the way, if I used the st.button(help), CSS will not work

Here’s a related post:

It works, and it can be applied to button size too. Thank you.
