You can simply attach it to your post, or post a reply with the file attachment (no .php extension, best is to zip it). Thanks in advance for sharing.

Actually CB uses standard joomla CSS classes, and some templates align correctly, others forget to align the headers left.

Try it with the default joomla template, and you will see them aligned correctly.

CB tries to use as much as possible the site template stylings and very few or no colors itself, so it blends in as well as possible to your site.

You might see that you have same problem for instance in the content lists on your site.

So probably the correct fix would be to add that to the CSS file in your site template.
