Different resolution ?

Question

How can you create a website compatible with multiple resolutions?
when i create a site in the playground with my phone then i open it with my computer it's different and when i edit it with my computer it's the same thing.
what is the solution?

Answer 1

modern phones have higher resolutions than desktop monitors (retina displays have twice the amount of pixels on the same area).
1. use relative units (%,em,rem,vh/vw);
2. use media queries (@media in CSS) to select different pics and styles depending on screen size and resolution. (js useragent helps to do that too, but CSS is faster).

Answer 2

Use more relative values then absolute
(more 80% then 80px)

Answer 3

You could also use bootstrap or APIs that use column layout in order to be mobile friendly
