Hi @keshavsingh2004! And welcome to our community! 
I’m not sure if you can add animations, as it’s not a something I’ve personally tried. But it should be possible to use that graphic as a static background image.
To learn how to do this, you can check out @andfanilo’s excellent tutorial:
Let me know how it goes!
Best,
Charly
currently i am using this animation
.stApp > header {
background-color: transparent;
}
.stApp {
background: linear-gradient(45deg, #3a5683 10%, #0E1117 45%, #0E1117 55%, #3a5683 90%);
animation: my_animation 20s ease infinite;
background-size: 200% 200%;
background-attachment: fixed;
}
@keyframes my_animation {
0% {background-position: 0% 0%;}
50% {background-position: 100% 100%;}
100% {background-position: 0% 0%;}
}
and calling using
with open("designing.css") as source_des:
st.markdown(f'<style>{source_des.read()}</style>', unsafe_allow_html=True)
Could you kindly provide me with guidance or code for incorporating the animation I’ve attached via this link into my project, considering that I am not proficient in front-end development?
@andfanilo might know the hack needed to add these animations in the background? 
i used streamlit components
import streamlit as st
from streamlit.components.v1 import html
