Reduce font-weight on news-link (latest entries enfold widget)

Hi, i am having a problem with font-weight on sidebar widget enfold-latest entries.
I added font-weight: normal; to my quick CSS, but it does not work.
The titles in the latest entries sidebar widget still are rendered bold.

This is the CSS i have added to manage my sidebar formatting:

.sidebar .widgettitle { font-size: 15px; }
.news-link {

font-size:15px;
font-weight: none;}

.widget.widget_categories{
font-size: 15px;
}
