To emulate the MIT page, you could use a blog app from the Weebly app store that sets up a masonry grid of "cards" that each link to your latest blog posts which contain the image, title, and snippet text seen in the cards. The hover effect would apply only to text that is a hyperlink which usually is the title text but may not be the snippet text. A little custom css on the app elements can essentially give you whatever hover behavior you'd like. Take a look at this blog app:
