Increasing pixel density on iPhone using CSS codes

I've encountered a dilemma while developing a responsive theme - all the pixels appear doubled on my iPhone, most likely due to its retina display.

My question is, should I create another style sheet (or use media queries) specifically for retina displays by adjusting values based on pixel density?

  • All margins are appearing twice as thick
  • Borders seem to be double in thickness
  • Font sizes are also visibly increased

Currently, all margins, borders, etc. are defined in pixels.

As a temporary solution, I am utilizing the following JavaScript to manage initial scale, which seems to be effective:

(function() {
  var meta = document.createElement("meta");
    meta.setAttribute('name','viewport');
    var content = 'initial-scale=';
    content += 1 / window.devicePixelRatio;
    content += ',user-scalable=no';
    meta.setAttribute('content', content);
    document.getElementsByTagName('head')[0].appendChild(meta);
})();

If anyone could provide me with a permanent fix for this issue, I would greatly appreciate it.

Edit:

I'm also using

<meta name="viewport" content="width=device-width, initial-scale=1, minimum-scale=1, maximum-scale=1, user-scalable=no" />
.

Answer №1

<meta name="viewport" content="width=device-width,initial-scale=1.0">
is the key to responsive design, especially when paired with media queries.
