@media screen font-size

Good morning.
Great job, simple and straightforward plugin to use.
I have a problem with the text size that I would like to set responsive, but I can’t find a solution.
I have applied CSS in different modes but nothing changes on screen.
An example of many so you can get an idea:

display: flex;
justify-content: center;
align-items: center;
background-color: rgba(255, 255, 255, 0.5);
padding: 20px;
@media screen and (min-width: 601px) {
  .crellyslider .cs-slides ul li span { font-size: 100%; }
}
@media screen and (max-width: 600px) {
  .crellyslider .cs-slides ul li span { font-size: 250%; }
}

I’m definitely doing something wrong, but I can’t find where.
Suggestion?.
Thanks
