# Inline Formatting

> Bold, italic, underline, strikethrough, highlight, inline code, links, and line breaks — all inline formatting options in Autype.

Autype supports all standard Markdown inline formatting plus additional marks for underline, highlight, and abbreviations.

## Bold

```markdown theme={null}
**bold text**
__also bold__
```

## Italic

```markdown theme={null}
*italic text*
_also italic_
```

## Bold + Italic

```markdown theme={null}
***bold and italic***
```

## Underline

```markdown theme={null}
++underlined text++
```

## Strikethrough

```markdown theme={null}
~~strikethrough text~~
```

## Highlight

Highlight text with a default highlight color:

```markdown theme={null}
==highlighted text==
```

Highlight with a custom color:

```markdown theme={null}
==highlighted text=={#ff6600}
==highlighted text=={yellow}
```

The color value inside `{...}` accepts any CSS color.

## Inline code

```markdown theme={null}
Use the `parseMarkdown()` function to convert text.
```

Content inside backticks is preserved exactly as-is — no further formatting is applied inside inline code.

## Links

```markdown theme={null}
[Link text](https://example.com)
[Link with title](https://example.com "Hover title")
```

<Tip>
  Links starting with `#` are treated as [internal references](/markup-reference/references), not external links.
</Tip>

## Line breaks

Use `<br>` for a line break within a paragraph:

```markdown theme={null}
First line<br>Second line<br>Third line
```

Without `<br>`, consecutive lines in the same paragraph are joined with a space.

## Inline variables

Reference variables inline with double curly braces:

```markdown theme={null}
Dear {{customer.name}}, your order #{{order.id}} is ready.
```

<Tip>
  See [Variables](/markup-reference/variables) for the full variable reference.
</Tip>

## Nesting

Inline formatting can be nested. For example, bold text can contain abbreviations or citations:

```markdown theme={null}
**The ~WHO~ recommends this approach @[smith2023, p. 42].**
```

The parser correctly handles abbreviations (`~ABK~`) and citations (`@[key]`) inside bold, italic, underline, strikethrough, and highlight marks.
