It would be easier to leave the slider widget area blank, and remove any widgets you have inside of it. Then you’ll need to remove the extra space/padding that is left behind from the “.slider-inner” in your css.
You’ll also have 40px of margin-bottom under the .head-wrap. You’ll need this for other pages, but you can remove that space specifically on the homepage by adding this –
.home .head-wrap {
margin: 0;
}
That will remove it from the homepage only, since you’ll need that space for other pages.
