Chicago Theme: mobile problem. From mobile phone the theme is distorted. Help me

Hi, I installed the Chicago theme on my new site with Wordpress. From pc everything goes ok but from mobile the theme turns out to be distorted, completely changed and even looks like another. I would be infinitely grateful if you could solve this problem and I apologize in advance for my total inexperience on the field, since this is my first site ... I leave the link below to see how the site is mobile. https://bluecreazioni.com/ Thanks so much, Mariagrazia. Please answer me at the email: bluecreazioni@virgilio.it
