Hacking font not posible in 1.27

Using Streamlit
1

hi,
with streamlit<=1.26, you could customize the font. Doing a “hack” like

theme_css = """
<style>
/* font */
@import url('https://fonts.googleapis.com/css2?family=Roboto&display=swap');

html, body, [class*="css"] {
    font-family: 'Roboto', monospace;
}
</style>
"""
st.markdown(theme_css, unsafe_allow_html=True)

But now, in streamlit==1.27, this doesn’t work anymore. In particular, markdown widgets (among others) doesn’t inherit.
Is this desired behavior?

thanks

font is part of theming with streamlit you look over doc to theme your app with fonts and importing font
streamlit theming docs

Native font theming, only supports “sans serif”, “serif”`, and “monospace”. Which is very limited. With the hack, you could (in <=1.26) use other standards (like “roboto” in the example), and give more proper personalization

Hi @iuiu

Similar to what you have implemented, this still works for me in the latest Streamlit version:

st.markdown("""
  <style>
    @import url(https://fonts.googleapis.com/css?family=Open+Sans:400,700,400italic,700bold);
  </style>
""", unsafe_allow_html=True)

And this is inherited to all widgets?

Cause with 1.28 doesn’t seem to work for met all (for <=1.26 yes)

One below seems to work with st==1.28

<style>
/* font */
@import url('https://fonts.googleapis.com/css2?family=Roboto&display=swap');

*, *::before, *::after {
    font-family: 'Roboto', sans-serif;
}
</style>
