change the fontsize when exporting to HTML, header not really changed

[Uwe Brauer]

Hi

I am using something like this in my org files that I want to export to
HTML:
,----
| 
| #+LANGUAGE: 
| #+EXPORT_FILE_NAME: /home/oub/Desktop/blabla
| #+OPTIONS: toc:nil
| #+HTML_HEAD_EXTRA: <style>*{font-size: 108%;}</style>
| 
| * This is the first header
| 
| Some text
`----

Now some text is changed as expected the text in the header not really.

Any idea what would be a more appropriate setting?

Thanks and regards
