Tightening up a template to remove spaces between lines


At the moment the posts on my blog classiccarsv.blogspot.com have spaces I wish to remove as follows:

What I would like help with is coding that allows me to close the spacing between the title of each post, the body of the post, and the footer info. I would also like to have just the 3 lines of info as currently shown followed by “read more” to open in a new window with additional details for each car.

I am sure this can all be done, but I am rather racking my brains (I’m a bass player, not a programmer…)
