Our class was assigned a project to make a website for an already existing company. I built mine using html5-boilerplate, and now the teacher is accusing me of plagiarism. They said it's a template and templates aren't allowed. I've built the entire website by myself. I created the layout by myself even though they accuse me of stealing existing elements because the stylesheet was already filled with css, and the entire interactive slideshow I built was without even consulting tutorials on the internet or using Javascript snippets from somewhere else.

Now, one of the teachers previously told me that using Bootstrap was allowed, so once they confirm that he actually said that, then there's no more discussion left.

However, I'm bothered by this and I'm genuinely curious whether using html5-boilerplate for this class assignment can be viewed as plagiarism. This assignment was to demonstrate that we're capable of building a website, and I think I'm more than capable of doing that. What does HN think?
