Hide div element when screen size is smaller than a specific size

You can do this with CSS:

@media only screen and (max-width: 1026px) {
    #fadeshow1 {
        display: none;
    }
}

We’re using max-width, because we want to make an exception to the CSS, when a screen is smaller than the 1026px.
min-width would make the CSS rule count for all screens of 1026px width and larger.

Something to keep in mind is that @media queries are not supported on IE8 and lower.
