All visually displayed text involves typography – whether it’s on paper, a computer screen, or a billboard. In simple words, it’s the way a text is visualized. Whether you write “Hello, how are you?” in your notebook with a pen, or write that in your text editor inside your computer the text remains the same. But what is different is the way the text is written visually.
