I am developing a website and need to be able to see what the pages look like at browsers' default zoom levels. Most desktop browsers allow you to manually set the browser zoom level using a menu or CTRL + Mousewheel. In mobile browsers you can pinch the screen to change the zoom level.
The problem I am having is that I can't figure out how to reset the zoom level to its default level on my mobile phone. I am having this problem in Microsoft Edge and UC Browser. The browsers also "remember" the zoom levels from the last time you visited the page, which means reloading the page doesn't help..
How do I reset the zoom level to its default in these and other mobile browsers?
My OS is Windows Phone 10 running on a Lumia 635.
