Hi @Aritra I used the following code to set a background image for my app:

page_bg_img = f"""
<style>
[data-testid="stAppViewContainer"] > .main {{
background-image: url("https://i.postimg.cc/4xgNnkfX/Untitled-design.png");
background-size: cover;
background-position: center center;
background-repeat: no-repeat;
background-attachment: local;
}}
[data-testid="stHeader"] {{
background: rgba(0,0,0,0);
}}
</style>
"""

st.markdown(page_bg_img, unsafe_allow_html=True)

Hope this helps

@Oleksandr_Arsentiev Thank you for your response. You are setting a particular image to the background, I want to change the app background colour using different shades of liner-gradient and all, as shown in the YouTube video below. How to achieve it without using an image ?
