How to prevent (bootstrap) fixed top navigation from zooming on mobile

Question

When using the fixed top navigation of bootstrap 3, I noticed that when users use the native zoom on mobile, the top navigation also becomes very large. This leads to a pretty p

Answer 1

Keeping Bootstrap's navbar-top-fixed from zooming on mobiles

The final result:

On mobile devices only, is possible to calculate the zoom factor as the ratio of window.innerWidth and the screen width, as shown in [2]. When the user toggles zoom, the resize event is triggered; moreover, when a page is reloaded that was previously zoomed, the zoom factor is maintained. Thus, one use jQuery to dynamically update CSS transforms that keep the header in shape. Note that, with position: fixed, a transformation of the origin is also required. Applying class device-fixed-height to the bootstrap nav and device-fixed-width to brand logo and hamburger icon then produce very close to the desired result.

• Bug: As the page is zoomed, the hamburger icons still moves a bit to the left. Any suggestions how to fix it are appreciated!
• Tested on: Android 4.4
