Where do academics obtain HTML website templates with no attribution? I have noticed that most .edu domains have a very "academic" looking simple HTML websites (Do academics look down on well-designed academic websites?) for professors and departments. My graduate school follows a template for the main department website and the professors and graduate students upload their own HTML websites on their sub domains.

I was recently tasked with uploading a simple HTML website for our group's research page. I have created websites before but my advisor asked me to put in minimal effort as I am busy writing research papers right now and should not be spending a whole lot of time playing with HTML and CSS.

I have noticed that a lot of professors have the same minimalist design of HTML websites. I know professors are pressed for time and so will adopt a minimalist HTML template and tweak it.

My question is: are there known resources where free simple HTML templates are available that require no attribution? I found several HTML templates that require attribution (linking back) to original designer and I would like to avoid that as I need something very simple that I can tweak.

I understand that professors might be writing the HTML from scratch. But if someone knows of a template I could use, that would be great.
When I was looking for a CSS style for my personal academic website, I got a recommendation to use Twitter Bootstrap. Then, I bascially ripped only the style out of it, but acknowledged them in the page footer.

As I just checked, you can directly link to their style without copying it locally and the code is licensed under an MIT license.
