CSS for the JioPhone 2

Target this screen size in CSS (portrait):

@media (max-width: 240px) {
  /* JioPhone 2 and smaller */
}
@media (min-resolution: 1dppx) {
  /* high-density screens: serve sharper images */
}

Design for ranges, not single devices: many phones share the same viewport width (for example 240 px).

Frequently asked questions

What is the viewport size of the JioPhone 2?

240 × 320 CSS pixels in portrait and 320 × 240 in landscape.

What is the screen resolution of the JioPhone 2?

About 240 × 320 physical pixels: the viewport multiplied by the device pixel ratio of 1.

Why is the viewport smaller than the screen resolution?

Phones pack several physical pixels into one CSS pixel (the device pixel ratio) so text stays readable. Websites lay out in CSS pixels; images can use the extra pixels for sharpness.
