+<!-- Taken from Hugo -->
+
+This article offers a sample of basic Markdown syntax that can be used in Hugo content files, also it shows whether basic HTML elements are decorated with CSS in a Hugo theme.
+
+## Headings
+
+The following HTML `<h1>`—`<h6>` elements represent six levels of section headings. `<h1>` is the highest section level while `<h6>` is the lowest.
+
+# H1
+## H2
+### H3
+#### H4
+##### H5
+###### H6
+
+## Paragraph
+

+
+## Blockquotes
+
+The blockquote element represents content that is quoted from another source, optionally with a citation which must be within a `footer` or `cite` element, and optionally with in-line changes such as annotations and abbreviations.
+
+#### Blockquote without attribution
+
+> Tiam, ad mint andaepu dandae nostion secatur sequo quae.
+> **Note** that you can use *Markdown syntax* within a blockquote.
+
+#### Blockquote with attribution
+
+> Don't communicate by sharing memory, share memory by communicating.<br>
+> — <cite>Rob Pike[^1]</cite>
+
+[^1]: The above quote is excerpted from Rob Pike's [talk](https://www.youtube.com/watch?v=PAAkCSZUG1c) during Gopherfest, November 18, 2015.
+
+## Tables
+

+#### Inline Markdown within tables
