bottom-center large text

Hello. I am trying leave a text in the left middle zone (margin), but there are a long text and get weird results. I will add an Example:

`@left-middle { content: "Texto de Prueba. Texto de Prueba. Texto de Prueba. ";}`
With this, I get these text in the correct zone multilined)

Then, I try make it vertical:
`@left-middle {
content: "Texto de Prueba. Texto de Prueba. Texto de Prueba. ";
-webkit-transform: rotate(-90deg);
-moz-transform: rotate(-90deg);
-ms-transform: rotate(-90deg);
-o-transform: rotate(-90deg);
transform: rotate(-90deg);
}`

Finally, I try make it single-line:
```
overflow: hidden;
white-space: nowrap;
```
And all text move to middle screen instead the left, this is caused by white-space property, any idea?:
