alt Hacker News> I researched and tested this extensively the other day. `<meta name="viewport" content="width=device-width">` is all you need.
This is incorrect. Try adding an <img> that's wider than the device width. Then the whole page gets zoomed and the text unreadably small.
The same will happen regardless in the case of content extending beyond the width of the viewport. With `initial-scale=1` it'll be a horizontal overflow, without it'll zoom out. I argue that the latter is preferable (https://vale.rocks/micros/20260908-1315) but either way should never reach users due to the usability fails and major accessibility issues.
