**Note**: Prior to Gitea 1.12 there was a single `markup.sanitiser` section with keys that were redefined for multiple rules, however,
there were significant problems with this method of configuration necessitating configuration through multiple sections.
## Customizing CSS
The external renderer is specified in the .ini in the format `[markup.XXXXX]` and the HTML supplied by your external renderer will be wrapped in a `<div>` with classes `markup` and `XXXXX`. The `markup` class provides out of the box styling (as does `markdown` if `XXXXX` is `markdown`). Otherwise you can use these classes to specifically target the contents of your rendered HTML.
And so you could write some CSS:
```css
.markup.XXXXX html {
font-size: 100%;
overflow-y: scroll;
-webkit-text-size-adjust: 100%;
-ms-text-size-adjust: 100%;
}
.markup.XXXXX body {
color: #444;
font-family: Georgia, Palatino, 'Palatino Linotype', Times, 'Times New Roman', serif;
font-size: 12px;
line-height: 1.7;
padding: 1em;
margin: auto;
max-width: 42em;
background: #fefefe;
}
.markup.XXXXX p {
color: orangered;
}
```
Add your stylesheet to your custom directory e.g `custom/public/css/my-style-XXXXX.css` and import it using a custom header file `custom/templates/custom/header.tmpl`:
```html
<link type="text/css" href="{{AppSubUrl}}/css/my-style-XXXXX.css" />
```
