st.chat_input was changed in this release to allow placing it in different locations or having more than one on a page. CSS hacks aren’t officially supported, and so may break on any release. If you need help figuring out the adjustment for the new version, feel free to create a new topic with an executable snippet to show what you had before and how it’s not working for 1.31.0.

Can you make a new topic in the Using Streamlit category to make sure your questions gets a proper discussion of its own? If you include a screen shot of the effect with and without the CSS, that will save some time in answering your question.

with st.expander("🧭 Menu"):

    st.page_link("Home.py", label="Home", icon="🏠", use_container_width=True)
    st.page_link("pages/0_Introduction_Demo.py", label="Introduction Demo", icon="1️⃣", use_container_width=True)
    st.page_link("pages/1_Dashboard_Demo.py", label="Dashboard Demo", icon="2️⃣", use_container_width=True)
    st.page_link("pages/2_Interactive_Demo.py", label="Interactive Demo", icon="3️⃣", use_container_width=True)

In my case this caused streamlit-image-select to stop loading new images whenever they came. We use st.session.state in components, not query params.
