What is HTML?
HTML is just a language to structure the content of a document by using tags and attributes. Luckily it doesn't require any compiler to run it just like C++, It requires only an ID and a browser. Here ID refers to the code editor such as VS code, it can be edit even in notepad but while saving the document an extension should be .html i.e (project 01.html).

What's the basic difference between HTML and HTML5?
HTML is easy to use and execute in almost all browsers. Whereas HTML5 cannot be run by older browsers such as Mozilla Firefox version 2 and 3.6.
HTML supports basic tags such as div and span which don't define the content inside the tags well whereas HTML5 has semantic tags which are self-explanatory such as header, nav, form, table, footer, article and so on. This helps the browser as well as another developer to understand the webpage more properly, as a result, it ranks in SEO.
HTML5 is still in the developing phase. So, we must be updated for new features in HTML5. Hence the revolutionary thing in HTML5 is the support of multimedia content i.e audio, video, and image as well as a canvas which allows the user to draw and edit that has been already used by multimedia editing tools such as Canva and Figma.
