WordPress WYSIWYG editor on demand, responsive

Using the following code to FORCE the buttons to wrap when the width of the editor hit a certain width, I used this code:

where single-movie-row is the container holding my WYSIWYG

.single-movie-row .mceToolbar td {
    display:table-row;
    float: left;
}
.single-movie-row .mceToolbar td:nth-of-type(11){
    clear: left;
}
