Creating a Custom Blog Post

[ElizabethPW]

I'm attempting to create a section of my site for specific articles and want to know if I have to ability to create a custom "blog post" template. Here's the details:

I have a category created for my articles - in this case "tutorials". I have a page_blog.php template created specifically for this category. I have this page_blog.php template set to display only the post excerpts.

Now - I would ultimately like to have the posts in that specific category appear on my site WITHOUT the sidebars. SO - I have the page template listing post excerpts. When the visitor clicks on the blog post title they want to read, it opens the blog post in a new page. The new page is displayed automatically in the standard with-sidebars layout. I would like for posts in this category (and only in this category) to be displayed without the sidebars.

Is there anywhere in the coding that I can connect a specific category to display posts in full-width?
