Advice generator using vanilla Javascript, SCSS and AXIOS

Hi, all! I am happy to complete this project, but I want to ask you something... in the browser, I can see the responsive design working correctly, but when I see the website on my iPhone, it's not working well, it's like the responsiveness is not applied... and I don't know why. This isn't happening with Android. Maybe if one of you has IOS and wants to test it, or give me any idea of what is going on, I would greatly appreciate it!
