KaiOS is a web-based operating system for mobile phones based on Linux.  It is forked from B2G OS (Boot to Gecko OS), an open source community-driven fork of Firefox OS, which was discontinued in 2016. It is written in HTML, CSS and JavaScript.
KaiOS is specifically designed for non-touchscreen phones, it supports many modern social applications like Facebook, twitter and WhatsApp. It also brings support for 4G LTE, VoLTE, Wi-Fi, GPS and so many other smartphone features, and since it's a web-based OS, it brings about longer battery life to non-touch devices with optimized user interface, less memory consumption. It also supports OTA(Over-the-air)updates and a dedicated marketplace called the KaiStore, which enables users to download games and applications.

In March 2020 Mozilla and KaiOS Technologies announced a partnership to update KaiOS with a modern version of the Gecko browser engine and more closely aligned testing infrastructure. This change should give KaiOS new features, including TLS 1.3, WebGL 2.0, Progressive Web Apps and modern JavaScript and CSS features.

CSS

by
CSS(Cascading style sheets) is the second major language of the web.  Cascading Style Sheets (CSS) is a styling language. It is the language used to style markup languages e.g HTML documents. CSS is an essential language in web development alongside HTML and JavaScript. CSS can be used to style HTML documents in three ways: inline, internal and external. The inline CSS is written on the particular HTML tag, styling a single HTML property. <ADD IMG> The internal CSS consist of the complete styling of a HTML document written in the HTML file. <ADD IMG> The External CSS is written completely in a .css file, with linking from the HTML file. External CSS is most recommended when coding because it makes your work cleaner and neater.
