We do not currently have those classes in the default tecton style sheet. I will write a ticket to get that added. I the mean time the break points tecton uses is:

$breakpoint-xs: 480px !default;
$breakpoint-sm: 768px !default;
$breakpoint-md: 992px !default;
$breakpoint-lg: 1200px !default;
$breakpoint-xl: 1400px !default;

this style tag could be added to get those css classes where items are hidden on below certain widths:

<style>
@media screen and (max-width: 768px) {
    [data-tecton-module] .hidden-xs {
      display: none;
    }
}

@media screen and (max-width: 992px) {
    [data-tecton-module] .hidden-sm {
        display: none;
      }
}

@media screen and (max-width: 1200px) {
    [data-tecton-module] .hidden-md {
        display: none;
      }
}

@media screen and (max-width: 1400px) {
    [data-tecton-module] .hidden-lg {
        display: none;
      }
}

@media screen and (max-width: null) {
    [data-tecton-module] .hidden {
        display: none;
      }
}

</style>
