In the Twenty Eleven theme for the single page posts it has two H1 tags. It has the blog title in a H1 tag and it has the post title in a H1 tag. I am looking for a way to chage the h1 tag for the blog title on single post pages to something else (div or h2). I believe this would be done in the header.php and/or single.php. From what I read it is a matter of replacing some code. Does anybody know how to do tis properly?
please do not edit Twenty Eleven directly but create a child theme http://codex.wordpress.org/Child_Themes to work with.
it is important to have an unedited default theme in case of serious problems. also, a child theme will help to keep any customisations when you next upgrade your wordpress version.
the blog title is done in header.php of Twenty Eleven:
