Hi GuiLois,

The thing I can help with is the reduction of the padding which we fixed with some custom CSS. Have you reduced the header padding as well?

Look below for our full code changes for the spanning slider. Next I am going to work on the floating text & actually having a nice looking button.

/**
* customization
*/
.flexslider .slides img {
width: 100%;
}
.slider-wide .widget.genesis_responsive_slider{
margin-bottom:0;
}
.slider-wide .wrap{
margin-bottom: 0;
padding-top: 0;
}
.head-wrap{
margin-bottom: 0;
}

Hope it helps.
