Css and templates

I’m using a classless css file (attricss.css) to style template pages. I added the relative link to the atricss.css file to base.html and it applies the css file to the index.html template, but not the blog.html or blog-page.html templates - it seems that the {% extends base.html %} tag in those templates is not including the css.

I can’t figure out why the index.html template is working with the css, but not blog.html or blog-page.html.

I have tried including the rel link to the css file in a {% block head %} / {% endblock} tag in base.html, blog.html, and blog-page.html, but index.html is still the only page that is getting the css applied.
