You can use PangoMarkupFormat (See https://developer.gnome.org/pango/stable/PangoMarkupFormat.html#PangoMarkupFormat).
e.g.
```
"format": "<span style=\"italic\">{}</span>"
```
## Multiple instances of a module
If you want to have a second instance of a module, you can suffix it by a '#' and a custom name.
For example if you want a second battery module, you can add `"battery#bat2"` to your modules.
To configure the newly added module, you then also add a module configuration with the same name.
This could then look something like this *(this is an incomplete example)*:
```
"modules-right": ["battery", "battery#bat2"],
"battery": {
"bat": "BAT1"
},
"battery#bat2": {
"bat": "BAT2"
}
```
## Minimal config
A minimal `config` file could look like this:
```
{
"layer": "top",
"modules-left": ["sway/workspaces", "sway/mode"],
"modules-center": ["sway/window"],
"modules-right": ["battery", "clock"],
"sway/window": {
"max-length": 50
},
"battery": {
"format": "{capacity}% {icon}",
"format-icons": ["", "", "", "", ""]
},
"clock": {
"format-alt": "{:%a, %d. %b %H:%M}"
}
}
```
## Multi output config
*Limit a configuration to some outputs*
```
{
"layer": "top",
"output": "eDP-1",
"modules-left": ["sway/workspaces", "sway/mode"],
...
}
```
```
{
"layer": "top",
"output": ["eDP-1", "VGA"],
"modules-left": ["sway/workspaces", "sway/mode"],
...
}
```
*Configuration of multiple outputs*
Don't specify an output to create multiple bars on the same screen
```
[{
"layer": "top",
"output": "eDP-1",
"modules-left": ["sway/workspaces", "sway/mode"],
...
}, {
"layer": "top",
"output": "VGA",
"modules-right": ["clock"],
...
}]
```
*Rotating modules*
When positioning Waybar on the left or right side of the screen, sometimes it's useful to be able to rotate the contents of a module so the text runs vertically. This can be done using the "rotate" property of the module. Example:
```
{
"clock": {
"rotate": 90
}
}
```
Valid options for the "rotate" property are: 0, 90, 180 and 270.
