Make nav image zoom in on hover

[karindalziel]

I didn't figure out how to do this quickly

the code (borrowed from sparc) will be something like this

.section-nav-image {
 background-position:center;
 background-size:800px 600px;
 display:block;
 margin-left:-15px;
 margin-right:-15px;
 overflow:hidden;
 padding:0
}
.section-nav:focus .section-nav-image,
.section-nav:hover .section-nav-image {
 background-position:center;
 background-size:960px 720px;
 transition:all 0.5s;
 -webkit-transition:all 0.5s;
 -o-transition:all 0.5s;
 -moz-transition:all 0.5s
}

I think things look good the way they are, this feature is no longer required!
