I have selected the 'standard' format for a post:
I am now trying to edit the layout of posts, in index.php I can see the following line:
get_template_part( 'content', get_post_format()
In the directory of twentythirteen I see several content pages which I am assuming is the post layout for the different formats I can select in the post.
I would have expected to see a content.php or content-standard.php, but I can't find anything that affects the layout. Where is this file (if it exists)?
