2-line Tagline?

Hi

i use Customizr (free) on one of my websites, and its great!

i try to make e 2-line line by insertting <br /> in the text, but the tagline on the page does show the <br /> instead of breaking the line.

I used <b> </b> in a menue title, and that works! so, how can I get a line break in the tagline?
