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.

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

Any time the screen is less than 1026 pixels wide, anything inside the { } will apply.

Some browsers don't support media queries. You can get round this using a javascript library like Respond.JS
