### line-height
`line-height`: <length> The line height of every line in the text. `line-height` is the space between top and bottom. There is no relationship between `line-height` and `font-size`, as `line-height` is restricted by top and bottom, `font-size` is interpreted by glyph. Usually but not always, `line-height` and `font-size` with the same value will cause the text clipped.

+### word-wrap
+`word-wrap`:<string> `break-word` | `normal` | `anywhere`. This property determins word wrap mode. For Weex, `anywhere` means clipping at character boundaries, other values or by default we break at word boundaries.

`lines {number}`: 正整数，指定最大文本行数，默认值为0，表示不限制最大行数。如果文本不够长，实际展示行数会小于指定行数。
### line-height
-`line-height {length}`：正整数，每行文字高度。`line-height`是 top 至 bottom 的距离。`line-height`与`font-size`没有关系，因为`line-height`被 top 和 bottom 所限制，`font-size` 被 glyph 所解析。`line-height`和`font-size`相等一般会导致文字被截断。
