Emphases

@content
The easiest way of emphasising in continuous text is the semantic command `\emph{}` that can also be nested:

``` {.lang-tex .hljs}
\emph{If you have a whole bunch of 
important text with some \emph{even more 
important Text} hidden inside it, 
you can use nested emphases.}
```

@title 
Optical highlighting

@content
specifies exactly how to format the text:

<table>
	<tr><th>Name</th><th>Befehl</th></tr>
	<tr><td>Bold (bold face)</td><td>`\textbf{important}`</td></tr>
	<tr><td>Italics (italics)</td><td>`\textit{important}`</td></tr>
	<tr><td>Small caps</td><td>`\textsc{important}`</td></tr>
	<tr><td>non-proportional (teletype)</td><td>`\texttt{important}`</td></tr>
	<tr><td>slanted</td><td>`\textsl{important}`</td></tr>
	<tr><td>underlined</td><td>`\underline{important}`</td></tr>
	<tr><td>subscript</td><td>`\textsubscript{…}`</td></tr>
	<tr><td>superscript</td><td>`\textsuperscript{…}`</td></tr>
</table>

Nesting emphases

@content
Possible if the font contains the exact font style:

``` {.lang-tex .hljs}
\textbf{Very
    \textit{Important
        \textsc{Stuff}
    }
}
```

**Some well-meaning advice: Better Call ~~Saul~~ LaTeX!**

You want the entire document to look consistent?

Trust LaTeX’s defaults (font sizes of title, paragraphs, footnotes, etc.)!

This conversely means: Avoid fiddling around with font sizes manually.

Font size

@content
### `normalsize`
*	used for continuous text paragraphs
*	default: 10pt
*	can be modified in the preamble:

``` {.lang-tex .hljs}
\documentclass[12pt]{article}
```

Font size

@content
###	Preset font sizes

``` {.hljs .lang-tex}
{\<fontsize> some text}
```

Font sizes relative to `normalsize`:

``` {.hljs .lang-tex}
{\tiny         If}
{\footnotesize you}
{\small        can}
{\normalsize   read}
{\large        this,}
{\Large        you}
{\LARGE        don’t}
{\huge         need}
{\Huge         glasses.}

### Manual configuration possible

``` {.lang-tex .hljs}
\fontsize{<fontsize>}{<lineheight>}
\selectfont
```

<p data-category="Example"></p>

``` {.lang-tex .hljs}
This is text in normal font size.

\fontsize{1cm}{0.9cm}\selectfont
This is a ginormous passage.

\normalsize
Back to normal.

URLs

@content
The `hyperref` package provides an `\url{}` command that reproduces URLs

*	letter by letter
*	using line breaks without hyphens
*	using a font with well-distinguishable characters
*	as a clickable link in the PDF

``` {.lang-tex .hljs}
\url{https://www.latex-project.org/}
```

@title
Emphasising text

@content
*	**Emphasise** the words *Rekursion* and *rekursiv* in `exercises/text-markup/markup.tex` using `\emph{…}`.
*	Make the **URL** in the text clickable. 
*	Of course, you can also experiment with the other **text markup** possibilities. However, remove them afterwards, if you want to have a clean document.
