Emphases

@content
Continuous text can be emphasized with `\emph{}`:

``` {.lang-tex .hljs}
\emph{Emphasize important 
\emph{and even more important} text}
```

Furthermore, optical highlighting can be used.

<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>underlined</td><td>`\underline{important}`</td></tr>
</table>

Better Call LaTeX!

@content
<div class="box warning">
**Some well-meaning advice**

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.

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 *Recursion* and *recursive* 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.

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.}
```

@title
Ragged alignment

@content
By default, LaTeX sets text in full justification, but it is possible to activate ragged alignment.

``` {.lang-tex .hljs}
\raggedright … \raggedleft …
\centering …
```

Alternatively, we can use dedicated environments:

``` {.lang-tex .hljs}
\begin{flushleft}  Text \end{flushleft}
\begin{flushright} Text \end{flushright}
\begin{center}     Text \end{center}
```

<p data-category="Caution!">Proper ragged alignment is even more difficult than good justification, so better avoid it.</p>

@title
Indentation and spacing

@content
* paragraphs are usually indicated by first-line indentation (`\parindent`)
* we can decide to use paragraph spacing (`\parskip`) instead (!)
* both parameters are customisable:

``` {.lang-tex .hljs}
\setlength{\parindent}{0pt}
\setlength{\parskip}{1em
    plus  .5em % permitted stretch
    minus .5em % permitted compression
}
```

* `\noindent` allows us to disable first-line indentation for a given paragraph
