  • It’s up to page to support small sizes, not Edge. Not sure why this was reported to us.

  • Nope. I can confirm this issue is related to Edge, not particular websites. Take blank page with only 3 lines of code and no CSS:


    Open it in F12, and resize the browser window down to it’s smallest. You’ll be at about 320px. Inspect the html element, go to the Computed tab, and look at its width --> 372px.

    In other words, Edge renders the page at a minimum of 372px wide even when resized smaller.

  • Same happening here. For example if you use @media (max-width: 372px) the query will work, anything below that width wont.

  • Same here!
    For sizes smaller than 372px, web pages are not renderer correctly.
    It’s seems that edge browser don’t resize, or dispatch the resize event.
    Other browser do it correctly for all sizes
