Html is used only for web based applications or for console applications also?

Answer 1

Html is not a programming language, you can not write any applications using only html at all.

Answer 2

Nope, HTML stands for Hyper Text Markup Language. it used for simple things like font color and size, background, and other visual aspects of a website. The furthest you could go with an HTML code is a simple website with basic depth and shapes. C++, Java, php, etc are needed to further make use of HTML.
