Can adjusting the viewport by using touch controls alter the size of the viewing screen?

When I tried to zoom in on a webpage using touch instead of the keyboard shortcut Ctrl +, I noticed that the elements stayed the same size but the screen itself was enlarged. It seems like this method does not affect the size of the viewport.

However, when using Ctrl +, the view changes from desktop to mobile if zoomed in too much, and the elements adjust accordingly.

I'm curious about how the viewport behaves when zooming in on a webpage using touch?

Answer №1

To determine the current dimensions of your viewport, you can utilize the code snippet below:

let width = Math.max(document.documentElement.clientWidth, window.innerWidth || 0);
let height = Math.max(document.documentElement.clientHeight, window.innerHeight || 0);

Keep in mind that the results may differ depending on the device and browser being used.
