Compressing a blog into a preview using tumblr_api_read

Here is what I have currently working. I would like to make it look more aesthetically pleasing, so not finish words in mid word. Also not have the two previews be so much larger than the other.

Ideally there would be a preview of two on the right (shorter) and then the one on the left (most recent) would show as much needed to make it equivalent height / length as the two on the right.

            function compressBlog(post, length) {
                    var count = length-100;
                    var blogContent = tumblr_api_read["posts"][post]["regular-body"].substring(0, length);
                    for (var i = length - 100; i <= length; i++) {
                        if (blogContent[i] == "<") {
                            break;
                        }
                        count++;
                    };
                    var blogPreview = tumblr_api_read["posts"][post]["regular-body"].substring(0, count);
                    return blogPreview;
