The layout is inconsistent when I open a blog on the index page, spot an interesting article, and click on it to get onto the detail page. On the detail page, the font size is a lot bigger. Lists are intended on the detail page, not the index page. There is a margin between list items on the detail page, not on the index page. The date is gray on the detail page, not the index page.
There are wanted layout differences between the index page and the detail page, like the positioning of the blog title, etc. But these differences seem unwanted and result in an inconsistent look and feel. I highly recommend keeping the text layout the same, independent of the page I’m looking at.
