How to reduce the font on IOS using the zoom style?

Question

iPhone

Greetings! the site has a map block that is reduced to 960px. The site is adaptive, you need to somehow reduce it and push it up to 320px. Scroll options are not suitable. I decided to use the zoom style, everything is fine on android and the picture fonts have all decreased as it should. On IOS devices. The font is the same size. I set the style to the parent of the entire map.
Below is a screenshot of how it is displayed on android

A photo from an iPhone, the house number falls down because the font does not decrease and is transferred below

Answer 1

zoom is not cross browser, use transform: scale(0.8)
