Use one big image for background or multiple ones in Cordova?

I'm building a Cordova app for both iOS and Android so naturally there are a lot of different screen sizes.

Some of my views have a full background image. My question is:

Is is better to use one big image that will cover the largest potential device and just use that for all devices, or use a lot of different images assigning each one to the right device using media queries?

Just looking for best practice here.

Solution

  • I recommend using an image that is 2732 x 2048 (largest iPad screen size today) combined with cover, percentage, or viewport background css sizing. For example:

       http://play.ionic.io/app/094f73be9047

    css

    ion-content {
  background-image: url(https://upload.wikimedia.org/wikipedia/commons/6/6c/Keeny-creek-wv-autumn-waterfall-scenery_-_West_Virginia_-_ForestWander.jpg);
  background-size: cover;

  text-align: center;
}

ion-content p {
  padding: 20px 0;
  color: white;
  font-weight: 100;
  font-size: xx-large;
}

    html

    <!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">

      <ion-content class="padding">

        <button class="button button-positive">I'm a button</button>
      </ion-content>
