Compact HTML


Compact HTML, often abbreviated as cHTML, is a simplified version of HTML designed for smaller devices like mobile phones and PDAs. It omits certain elements like tables, image maps, and styles that regular HTML includes. This allows it to provide efficient performance while using less bandwidth, making it suitable for devices with limited resources.


The phonetics of the keyword “Compact HTML” is /kɒmˈpækt eɪtʃ tiː ɛm ɛl/.

Key Takeaways

Main Takeaways about Compact HTML:

  1. Compact HTML is a subset of HTML for small devices.
  2. It was originally designed for use in PDAs and other mobile devices with limited capacities.
  3. The key characteristics include smaller footprint, reduced functionality, and focus on essential features only.


Compact HTML, often abbreviated as cHTML, is especially significant in the realm of technology due to its role in facilitating internet access on small devices such as mobile phones and PDAs. This simplified version of HTML — the standard markup language used for creating websites — is designed to work on devices with limited capacities. cHTML excludes certain features of regular HTML that could overtax less powerful devices, such as image maps, background colors and images. Hence, it plays a critical role in ensuring web access is more inclusive and widespread, accommodating a myriad of devices beyond just personal computers. By doing so, it has been pivotal in the evolution and growth of mobile internet, providing the basis for mobile web browsers to display web pages efficiently without compromising the user experience.


Compact HTML, also known as cHTML, is a subset of the standard Hypertext Markup Language (HTML) specifically designed for limited capacity devices such as mobile phones and PDAs. The purpose of this lightweight version of HTML is to cater to the specialized needs of small devices by simplifying the web content that is delivered, thereby promoting speed and efficiency of the content displayed, despite the device’s constraints in power, screen size, and network bandwidth costs. cHTML is predominantly used for internet services on mobile devices, especially in conjunction with i-mode, a popular internet service for mobile phones in Japan. With cHTML, web developers can create interactive websites that work flawlessly on a variety of devices with lower specifications. It substantially eliminates functionalities not needed for mobile viewing while emphasizing necessary ones like text formatting, input forms, and basic image embedding – clearly focusing on making the internet more accessible to users on the go.


1. Mobile and Embedded Devices: One of the real-world applications of Compact HTML (cHTML) is its use in mobile and embedded devices such as smartphones, tablets, handheld gaming devices, etc. cHTML allows these devices with limited capabilities to browse web pages that have been specifically designed and formatted for smaller screens.2. Online Interactive Services: Certain online interactive services like banking, reservation, shopping systems, etc., use cHTML for creating their mobile versions. It allows faster navigation and improves servers’ efficiency by reducing data volume.3. Internet of Things Devices: cHTML also finds its application in various IoT (Internet of Things) devices. Devices like smart refrigerators, smart TVs, and healthcare monitoring devices often use compact HTML to interact with web pages efficiently despite their limited processing capabilities.
