Studio theme sitewide header is always aligned center, need to align left

Hi there,

I'm setting up the Studio theme on a website and need the sitewide header to be aligned left. It is currently aligned in the center. Please help! This is the part of the code I tried to change.

<div id="strapline"><!-- start #strapline -->
<h1>
HEADER TEXT
</h1>

I tried putting <div style="text-align:left;"> around the <h1> tag and around the text, but it didn't help.

Thanks,
Christian
