Font size can be changed by using the following additions. The general font size is dependent on the [default font size](https://gitlab2.informatik.uni-wuerzburg.de/decker/decker/-/wikis/WIP:-List-of-all-meta-options)(`font-size-base`) set as [meta option](https://gitlab2.informatik.uni-wuerzburg.de/decker/decker/-/wikis/Custom-Meta-Options).
| MD Code | Size |
| ----------- | ---- |
| {.xx-large} | +60% |
| {.x-large} | +40% |
| {.large} | +20% |
| {.medium} | ---- |

# Highlighting
## Text Highlight
To highlight text enclose `<mark>` your text in `</mark>` brackets.
```
This splendid palace of the Prince-Bishops is one of the finest secular Baroque buildings in Germany. Built between <mark>1720 and 1744</mark>

## Highlight Blocks
To highlight blocks add highlight definition to a level 2 heading.
To create a Code Block surround your verbatim text with `~~~` or ` ``` `. Alternatively each line of the Code Block can be indented by four <kbd>SPACE</kbd>.
You can also write your emojis as text representation and decker will translate them to an image. For a cheat sheet to the text representation see this [github list](https://gist.github.com/rxaviers/7360908).
## Mathematics
Decker uses MathJax to display math equations. For further information take a look at the [MathJax documentation](http://docs.mathjax.org/en/latest/index.html).
### Inline math
To write formulas as part of text put your equation in `$` brackets.
```
To $\infty$ and beyond!
```
To $`\infty`$ and beyond!
### Display math
To write expressions that are not part of text or paragraphs enclose them in double `$$`
