verifying the user's screen dimensions

I'm currently exploring ways to customize the appearance of my website based on the viewer's screen resolution. I am interested in potentially optimizing the layout for vertical screens on mobile devices, and horizontal screens for laptops. Additionally, I am considering adjusting the layout based on the ratio of vertical to horizontal resolution exceeding a specified threshold. Any ideas or recommendations on how I can achieve this customization or implement other strategies to enhance the viewing experience based on different screen types?

Answer №1

To adjust styles based on screen resolution, you can utilize media queries within your CSS files. Here is an example:

// styles.css
@media only screen and (max-width: 768px) {
  body {
    background-color: #000;
    color: #fff;
  }
}

For more information on this topic, you can refer to the Mozilla WebDocs or check out the links provided in another answer.

If you prefer using plain JavaScript, you can follow the approach mentioned in the following answer:

Answer №2

To achieve this, you can implement responsive design using media queries:

@media (max-width: 500px) {
  .root {
    background-color: lightblue;
  }
}
<div class="root">Hi, I am the root</div>

Alternatively, you could utilize javascript's Window: resize event for dynamic responsiveness like so:

addEventListener('resize', (event) => {
  if (window.height > 768)
    console.log("You are on desktop")
  else
    console.log("You are on tablet/mobile")
});
