# Emphasis - [Emphasis (typography)](<https://en.wikipedia.org/wiki/Emphasis_(typography)>) - According to _Chicago Manual of Style_, 17th edition - _Italics_ can shall be used in most of cases for emphasis or make words stand out in general, but rely primarily on sentence structure to do so. Never italicize a whole sentence. - **Boldface** and <u>underscore</u> are considered less appropriate in formal prose, especially in print. - FULL CAPS are only used ironically. - <small>SMALL CAPS</small> are used to express terms in some places. It's much more graceful than **FULL CAPS**. --- | Emphasis | Syntax | Intensity | Visibility | Compatibility | Usage | | ------------------------ | ------------------------ | --------- | ---------- | ------------- | ------------------- | | _italics_ | `*content*` | gentlest | good | Markdown | Word/Phrase/Title | | **bold** | `**content**` | gentle | poor | Markdown | Avoid | | <u>underscore</u> | `<u>content</u>` | gentle | good | HTML | Avoid | | `code` | --- | gentle | good | HTML | Avoid | | ==highlight== | `==content==` | strong | best | Markdown | Sentence | | ~~strike~~ | `~~content~~` | strong | best | Markdown | Deletion | | [[backlink]] | `[[content]]` | strong | better | Obsidian | Backlink | | quote block | `> content` | strong | best | Markdown | Quote/Cite | | <small>SMALL CAP</small> | `<small>CONTENT</small>` | stronger | best | HTML | Avoid | | FULL CAP | `CONTENT` | strongest | better | Text | Sarcastic/Emotional | | admonition/callout | `> [!note] content` | strongest | best | Obsidian | Paragraph |
