HTML5 themes with a Blog

I’ve been searching through the HTML5 templates & there are a lot of really nice templates. Many of them have a blog. My question is:

Is this a real blog, or is this a placeholder? I come from the wordpress world & understand the CMS aspect of a blog. However, do these HTML5 websites have a blog that just doesn’t have the functionality of wordpress (i.e. user management, deleting posts, etc)? Meaning, you can post, but don’t have CMS functionality. Or are these templates just showing what a blog looks like in their theme?

Thanks

You are right – “these templates just showing what a blog looks like in their theme” because most those HTML template will become wordpress themes
