Long blog post titles wraparound and overwrite beginning of line

On the page that lists all blog posts, posts with long titles are wrapping around, but on the same line, so that the beginning of the title is being overwritten by the end. The attached screenshot shows this. How can I set a property so that long titles will wrap to a new line?

Here is the published page exhibiting this behavior: https://ccmht.org/blog?offset=1507681830313
