fix responsive bug on site home

The site is [login to view URL] - To choose the option in the first checkbox you need to double-click, which would only take one. (The box with the cities appears when we write something. when we select a city, it is marked in blue. then we have to click on it again to fill the field) - Calendar appears in unfocused places on the screen the problem mostly occurs on the iPhone 5 The backend is in nodejs and the screen is mounted in ejs. However, the problem is basically in javascript / html / css. However, knowledge in ejs / nodejs is desirable, as I intend to hire for several other larger changes soon.
