Can't figure this out: can't change body text in multicolumn on mobile 😭(Dawn theme)

[Boyang]

Hello! 

website, I have been trying for days and can't figure this out😭. I have changed the font family and text alignment for the body text in multicolumn for desktop, but have been unable to change it for mobile. When I inspect elements, it's listed under root??? 

I have some css knowledge from college, but def not enough to understand how to change this. Any help would be appreciated!

Got the website link.

@media screen and (max-width: 749px) {
.multicolumn-card__info .rte {
    text-align: center;
    margin-top: 0px;
}
}

Please use that CSS in base.css file
