hentry error in style.css

hi, I found a “hentry” in the content section after sticky. since all the following line read entry, I suppose the “h” should be removed

.sticky {
}
.hentry {
margin: 0 0 20px;
-ms-word-wrap: break-word;
word-wrap: break-word;
}

.entry-header {
margin: 0 0 20px;
}
.entry-title {
margin: 0 50px 3px 0;
font-size: 2.4em;
line-height: 1.2;
}
