Change text alignment in features widget

I followed the directions from a previous thread trying to align text in the Features Widget, but it didn’t work. The default text aligns center (not sure why) and I’d like to change it to left. Below is what I did:

In the Attributes Widget Class line I entered:
features-widget-text

Then in my CSS Style sheets (I’m using a child theme), I entered:
/* Features Widget */

.features-widget-text .textwidget {
text-align: left;
}

What am I doing wrong? I even tried aligning the text using html within the text field in the widget, which worked when previewing, but disappeared when pushing live.

Thanks in advance!
