Prevent Hyphenation in Sidebar

How can I stop hyphenation in the sidebar widgets.

I’ve scoured the CSS and tried the CSS3 code but nothing changes. This is what I’m trying to use:

.widget {
-webkit-hyphens: auto;
-moz-hyphens: auto;
-ms-hyphens: auto;
hyphens: column;
line-height: 1.2857142857;
margin-bottom: 48px;
width: 100%;
word-wrap: normal;
}

Thanks,
Sharon.
