title: Literal Attribute Values
type: text/vnd.tiddlywiki
Literal attribute values can use several different styles of quoting:
* Single quotes (eg `attr='value'`)
* Double quotes (eg `attr="value"`)
* Tripe double quotes (eg `attr="""value"""`)
* No quoting is necessary for values that do not contain spaces (eg `attr=value`)
Literal attribute values can include line breaks. For example:
```
<div data-address="Mouse House,
Mouse Lane,
Rodentville,
Ratland."/>
```
By using triple-double quotes you can specify attribute values that contain single double quotes. For example:
```
<div data-address="""Mouse House,
"Mouse" Lane,
Rodentville,
Ratland."""/>
```
