If you want to hide it you can use JavaScript to add the hide style to it.

function checkboxHandler() {
    var el = document.getElementById('yourCheckBoxId');
    if(el.value){
       document.getElementById('sharePointId').setAttribute('style', 'display:none;');
    }else{
       document.getElementById('sharePointId').setAttribute('style', 'display:block;');
    }
}

If you were to use a nice JavaScript library like jQuery you can make this code simpler and add some sweet animations.
