TEXT COLUMNS ON MOBILE

Site URL: https://www.elevateptr.com/

Hi - is it possible to add css to this text box that I added columns to so on mobile the block shrinks and looks better vs. the letters wrapping like the attached image?

Add to Home > Design > Custom CSS

@media screen and (max-width:767px) {
div#block-1c9570fe5d6ce45f3858 * {
    font-size: 12px;
}
}
