Site returned a 404 when I clicked on your link…
Sorry! My site is http://www.nunobeja.com/pasta/
Thank you so much for taking a look!
I’m assuming you want to get rid of the header and footer and leave a small 13px space above and below the sliding content.
Getting rid of the header and footer as you suggested will work, however the gap does not remove because the sliding content appears to be dynamically set by the browser window size and embedded as an inline style.
I was able to force it up towards the top of the page with the following CSS
.home #main {
top:13px !important;
height: 98vh !important;
}
If you want to target a little more specifically you could also change the height attribute to
height: calc(100vh - 26px) !important
Bear in mind that these solutions will not work correctly in older browsers. Hope this helps
