Oxygen theme post title remove word-break

Please could someone advise me how I would stop words breaking at the end of each line of my posts in the Oxygen template.

The word photographer is broken so the r is on a sep line ….

When I look in web inspector the post title code is:

.hentry .entry-title, .page-template-front .hentry .entry-title {
margin: 0 0 0.15em 0;
padding: 0;
font-size: 1.333333333333333em; /* 16 / 12 = 1.333333333333333 */
text-transform: uppercase;
line-height: 1.4em;
border: none;
color: #111;
word-spacing: 2px;
word-wrap: break-word;
}

If I remove the word-wrap: break-word; bit the word photographer is joined together again. Hurrah – the problem I have is trying to implement this in my child theme css file ….

I have added this to my child theme but it does’t seem to work ….

/* Post titles
————————————————————– */
.hentry .entry-title, .page-template-front .hentry .entry-title {
word-break:normal !important;
word-break: keep-all; !important;
}

/* Post title color for home, archive and search page color */
.home .hentry .entry-title a:hover,
.page-template-front .hentry .entry-title a:hover,
.archive .hentry .entry-title a:hover,
.search .hentry .entry-title a:hover {
color: #9A9A9A;
word-break:normal !important;
}

/* Post title for other pages */
a, a:visited, .page-template-front .hfeed-more .hentry .entry-title a:hover, .entry-title a, .entry-title a:visited {
color: #0DA4D3 !important;
font-family: ‘Abel’, ‘Helvetica Neue’, Helvetica, Arial, sans-serif !important;
word-break:normal !important;
}

If there is anyone who can shed some light on this I would be very grateful …

Thanks in advance
