Reply To: Home Feature 1 (Left)

There is a width of 300px added that should either be removed or adjusted –

.home-feature-bg-alt .featuredpage .page,
.home-feature-bg-alt .featuredpost .post {
    float: left;
    margin: 0;
    overflow: hidden;
    padding: 0 0 5px;
    width: 300px;
}

This can be found on line 1403 in your style.css file.
