I've run into a problem after creating a OOTB blog in our environment where the web part zone "Blog navigator" and "Left" are floating into each other, giving the blog a strange look when trying to use the Inline template. The date CSS floats into the title. Trying to set the web part to a specific size does not help.
And when clicking on one of the archive categories, The message floats into the "Blog tools".
Is this a standard behavior? We have no custom master page nor custom CSS.
