Device emulation on Chrome

If you have encountered the problem of testing the layout for Retina screens (MacBook devices), tablets and phones - this documentation will help you.

Good practices for breakpoints

We recommend using the breakpoints from the Bootstrap documentation. It is clear that designers will not adapt to all breakpoints, but it is important to have at least the following:

• 375px — for phones (to 575px)
• 768px — for tablets (to 991px)
• 1200px – for laptops 13-14 inches
• 1400px – for laptops 15-16 inches

Important

For designer: Avoid 100% width layouts. Make a layout in a container, the indents for which will increase with the increase of screen.

For developer: It's still important to test the layout on ≥576px and ≥992px breakpoints, even when there is no adaptation from the designer

How to get your device data?

To do this, just save this simple html and open it in your browser:

<!DOCTYPE html>
<html>
  <head>
    <title>Check CSS Pixel Ratio</title>
  </head>
  <body>
    <h1>Check CSS Pixel Ratio</h1>
    <div id="devicePixelRatio"></div>
    <br />
    <div id="screenResolution"></div>
  </body>

  <script>
    function print(id, value) {
      var message = `<p>${value}</p>`;
      console.log("message = " + message);

      document.getElementById(id).innerHTML = message;
    }

    print("devicePixelRatio", `CSS Pixel Ratio: ${window.devicePixelRatio}`);
    print(
      "screenResolution",
      `Screen Resolution: ${window.innerWidth}:${window.innerHeight}`
    );
  </script>
</html>
