Changing the text style in the HTML is possible thanks to Cascading Style Sheets (CSS), the stylesheet language used to describe the presentation of a document in HTML.

CSS works in combination with HTML. We can create buttons, links, and other elements using HTML and then using CSS we can change those elements’ size, color, position, etc.

Where HTML defines the structure and content of a web page, CSS (Cascading Style Sheets) is the coding that underlies the appearance and formatting, from type sizes to columns and floating boxes.
