WAP also has sites written in WML like HTML-based sites.
WML is designed to handle issues like small display size, limited user input capabilities, narrowband network connection with high latency, limited memory and computational processing power.
WML is analogous to HTML in several ways because it is written in plain text format. However, because wireless devices are not the same in terms of display, processing power and button layout, some features are specific to devices that are incorporated in WML.
The following are some key features of WML as compared to HTML:
WML-equipped devices have the following characteristics:
