unable to display website similar to the demo is displayed on mobile

Hi Sangeeta, Greetings of the day! I used the Zubin Free theme and built my website with almost all my content. (Except my portfolio) It looks great on desktop. However, when I try to view it from my mobile phone, everything gets contracted. It would be great if you could kindly help me and please guide me where I may be wrong. Things, Im unable to display clearly are; 1) Please check the option SERVICES WE PROVIDE. The mobile view of the demo looks amazing in mobile, however, the changes i made aren't looking that good in mobile. 2) Drop down and search icons aren't appearing clearly. There might be some problem. 3) Is there a way we can make the Header Media responsive? The header media doesn't look that interesting on phone. Here's my website URL: https://www.sashainnovation.com/ I am planning to launch it on 1st January and I really want this to be done before that. Hoping for a positive response! Thanks and Regards, Akshay
