Remove text shadowing from Sticky

I want to remove the shadowing from the sticky/featured post text on my homepage, but I can’t find the right line in the style sheet to change. I am already using a child theme of Magazine Basic.

I managed to change the color of the background and the color of the text, but not the shadowing of the text. Here is what this section of the style sheet looks like right now:

/* =Sticky
————————————————————– */
.sticky {
background: #fff;
padding: 20px;
color: #636;
border-radius: 6px;
}

.sticky,
.sticky .entry-content img {
border: 2px solid #000;
}

.sticky p {
margin-top: 0;
}

.sticky .entry-meta,
.sticky .entry-meta a,
.sticky .entry-title,
.sticky .entry-title a,
.sticky h1,
.sticky h2,
.sticky h3,
.sticky h4,
.sticky h5,
.sticky h6 {
color: #336699 !important;
}

.sticky .post-category,
.sticky .post-category a,
.sticky .entry-title a:hover {
color: #ccc !important;
}

.sticky .post-category a:hover {
color: #ccc;
}

.sticky .entry-content {
border: 0;
padding: 0;
}

.sticky .entry-content a {
color: #000;
border-bottom: 1px dotted;
}

.sticky .entry-content pre {
text-shadow: none;
}

.sticky .more-link {
-moz-box-shadow: none;
-webkit-box-shadow: none;
box-shadow: none;
border-color: #222;
margin-bottom: 0;
}
