    Adding this answer because the comments in the accepted answer are getting too long and it's not complete. As already explained, the hidden-* classes no longer exist in Bootstrap 4 beta.

    "What exactly is hidden-sm-DOWN?"

    It no longer exists in beta, but it previous versions it meant "hidden on small and down". Meaning, hidden on xs and sm, but otherwise visible.

    If you want to hide an element on specific tiers (breakpoints) in Bootstrap 4, use the d-* display classes accordingly. Remember xs is the default (always implied) breakpoint, unless overridden by a larger breakpoint. Since xs is implied, you no longer use the -xs- infix. For example, it's not d-xs-none, it's simply d-none.

    • hidden-xs-down = d-none d-sm-block
    • hidden-sm-down = d-none d-md-block
    • hidden-md-down = d-none d-lg-block
    • hidden-lg-down = d-none d-xl-block
    • hidden-xl-down = d-none (same as hidden)
    • hidden-xs-up = d-none (same as hidden)
    • hidden-sm-up = d-sm-none
    • hidden-md-up = d-md-none
    • hidden-lg-up = d-lg-none
    • hidden-xl-up = d-xl-none
    • hidden-xs (only) = d-none d-sm-block (same as hidden-xs-down)
    • hidden-sm (only) = d-block d-sm-none d-md-block
    • hidden-md (only) = d-block d-md-none d-lg-block
    • hidden-lg (only) = d-block d-lg-none d-xl-block
    • hidden-xl (only) = d-block d-xl-none
    • visible-xs (only) = d-block d-sm-none
    • visible-sm (only) = d-none d-sm-block d-md-none
    • visible-md (only) = d-none d-md-block d-lg-none
    • visible-lg (only) = d-none d-lg-block d-xl-none
    • visible-xl (only) = d-none d-xl-block

    Also note that d-*-block can be replaced with d-*-inline, d-*-flex, etc.. depending on the display type of the element. More on the display classes in beta

    EDIT the hidden-* properties are removed from the bootstrap beta 4.

    You need to use the d-*-none (*= xl, sm, md, lg). Link

    For example:

    the class d-none will allow you something to be invisible on every screen.

    the class d-sm-none: will not be visible for small devices.

    the class d-md-none: will not be visbile for medium devices.

    the class d-lg-none: will not be visbile for large screen devices devices.

    For you, need to write this.

    <div class="container">
        <div class="row">
        <div class="d-none d-sm-none d-md-block col-lg-4 col-md-6 col-sm-12 col-xs-12">
            Some text here.
        </div>
    </div>
    

    Start with d-none add the screen that you want with d-*-block. Example if you want to display for md only, you should write class="d-none d-md-block".
