1. HTML is a set of markup symbols/codes placed in a file and then displayed via the world wide web. The physicist Tim Berners-Lee created the concept of HTML in late nineteen-ninety when he came up with the idea for an Internet-based hypertext system. These markup symbols and codes are used with the purpose and intention of aiding in the identification of structural elements like paragraphs, headings, and lists as well as for displaying media content on web pages. HTML is made up of several individual markup codes that can be referred to as "elements" or "tags," which are used to display text or alter the webpage in some way.

2. Really, no special software is necessary when it comes to creating a webpage. All you need is a sort of text editor such as Notepad, Notepad++, or even TextEdit and you can get started with DOCTYPE and so on.

From here, you will select File > Open > Browse and select your webpage file to open and test it out.
