/* set font size for all posts; center the title; and reduce space after it; removed word-breaks and added 4 lines for hyphen control–especially on mobile devices, 03/10 */
font-size: 19px !important;
margin-top: -14px !important;
margin-bottom: 14px !important;
text-align: center !important;
Apparently, it takes the last 4 lines. I tested each individually and hyphenation still happened. I think a non-hyphenated title looks better on a mobile device.
