I want my byline to be right-aligned with the last word in the title, but I can't figure out how to do it correctly.

In the examples, look for the small, pink text under the image. Some of these links contain vulgar language which may be considered NSFW.

It works for smaller titles (Example 1), but for larger titles, it just aligns to the right of the block (Example 2). For titles where the text is shorter than the byline, it works correctly by extending out past the text (Example 3).

Has anyone attempted this before? Does anyone have any idea how to make this happen?
