HTML, which stands for HyperText Markup Language, is the predominant markup language for web pages.
It provides a means to create structured documents by denoting structural semantics for text such as headings,
paragraphs, lists, links, quotes, and other items. It allows images and objects to be embedded and can be
used to create interactive forms. It is written in the form of HTML elements consisting of "tags" surrounded
by angle brackets within the web page content. It can load scripts in languages such as JavaScript
which affect the behavior of HTML web pages. HTML can also be used to include Cascading Style Sheets
(CSS)
to define the appearance and layout of text and other material. The W3C, maintainer of both HTML and CSS
standards, encourages the use of CSS over explicit presentational markup.
Embedding multiple nested lists
Nested lists can be tricky when constructing the source code.
