answer:My instinct is that CSS will not be able to help you with this…probably some scripting and HTML is in order. CSS will only change the look and feel of a page, not the function (having a short blurb that can link to the full post is a function kind of thing). I’m not particularly familiar with Tumblr theming, so I can’t give any specific help. Do you know of any themes that have this functionality, and can you look at the code to figure out how it’s done?
