Disabling Touch Simulation in Firefox Renders HTML/CSS Differently

I’m new to web-dev and don’t know if this is working as intended, but it seems odd to me. Briefly, disabling touch even simulation causes my webpage to be rendered differently (see attached photos). Is this due to my code, Firefox dev tools, or something else?

Thanks.

Solution

  • You need to add the following code to the head section (before title tag):

    <meta name="viewport" content="width=device-width, initial-scale=1">

    From HEAD

    • meta name="viewport" - viewport settings related to mobile responsiveness
    • width=device-width means that it will use the physical width of the device (instead of zooming out) which is good with mobile-friendly pages
    • initial-scale=1 is the initial zoom, 1 means no zoom
