I’m developing a web app for feature phones in Africa (non- smartphones whose screen size is usually 128 x 160 px (1.80″)).

I need to learn how to make the website responsive, or display properly for a screen size so small. I’m aware that regular CSS queries dont work well for feature phones, so any other suggestions?

This:

is something I read on the topic, but it’s vague for me to understand what changes to make in my CSS file (which is using bootstrap at the moment) Will really appreciate your help!

  1. You can either try things like foundation which you can use pre-made tables, and sections with pre-defined css properties:
    http://www.foundation.zurb.com/

    Or you can use percentages, width: 15%. So it will get the designated percentage of your device and calculate the correct size based on that.

    Also what your listed site is saying(google), it creates different css files based on your device. So when you use <link> to set your CSS file you can make it so certain devices use certain files:
    (Taken from Google):

    <link rel="alternate" media="only screen and (max-width: 640px)" href="http://m.example.com/page-1" />

  2. To make a website responsive we have to use CSS3 @media queries. Write @media queries for different screen sizes. But @media queries doesn’t support for older version browsers. In your case (non-smartphone) @media doesn’t work. I suggest create a sub domain for mobile phones like http://m.website.com and use javascript to redirect to mobile version site if user opens http://website.com .

    @media only screen 
      and (min-device-width: 128px) 
      and (max-device-width: 160px) 
     {
    
    /* Put your CSS Code for small screen */
    }
    

    Some useful articals about @media .
