### Text element
-Text elements can be created with a single style applied.
+Text elements can be created with an object as the first argument defining the 'text' content, 'x' and 'y':
```javascript
var text = draw.text({
text: "svg\nto\nthe\npoint.",
y: 0
});
```
-Styling text can be done using the 'font()' method which is both a setter and a getter:
+Styling text can be done using the 'attr()':
```javascript
-// get a single font property
-text.font('size');
-
-// set a single font property
-text.font('anchor', 'start');
-
-// set multiple font properties at once
text.font({
- family: 'Helvetica',
- size: 36,
- anchor: 'middle',
- leading: 1.5
+ 'font-family': 'Helvetica',
+ 'font-size': 36,
+ 'text-anchor': 'middle',
+ 'leading': 1.5
});
```
Changing text afterwards is also possible with the 'text()' method:
```
To get the raw text content:
```javascript
-text.content;
+text.attr('text');
```
-Setting attributes like fill, opacity, x and y is the same as other elements:
+The sugar.js module provides some syntax sugar specifically for this element type:
```javascript
text.attr({
- fill: '#333',
- x: 100
+ family: 'Helvetica',
+ size: 144,
+ anchor: 'middle',
+ leading: 1.5
});
```
