What is a blockquote in Markdown?

In Markdown, a blockquote is a way to indicate that a section of text is a quotation from another source. A blockquote is typically indented and highlighted with a vertical bar or other symbol, and it can be used to distinguish quoted material from the surrounding text.

To create a blockquote in Markdown, you can use the greater-than symbol (>) followed by a space at the beginning of each line of the quoted text. For example:

> This is a blockquote.
> It can span multiple lines and contain Markdown formatting.

When rendered, this would appear as:

This is a blockquote.
It can span multiple lines and contain Markdown formatting.

Blockquotes can be nested within other elements, such as lists or other blockquotes, to create more complex structures.
