Responsive Tables

Hi there!

I was trying to achieve responsive tables with Customizr but they are not working. I would like something like this, as seen here (https://sitesforprofit.com/responsive-tables-in-wordpress):

So that on mobile phones i could have tables formatted like the one on picture, since i believe its much more useful that way on small screens.

From that website i tried to add the code

@media screen and (max-width: 600px) {
table {width:100%;}
thead {display: none;}
tr:nth-of-type(2n) {background-color: inherit;}
tr td:first-child {background: #f0f0f0; font-weight:bold;font-size:1.3em;}
tbody td {display: block; text-align:center;}
tbody td:before {
content: attr(data-th);
display: block;
text-align:center;
}
}

to my child style.css but it has no effect.

Thanks and i think Customizr devs should add this as an option to Customizr settings!!
