Twitter Bootstrap 3: how to use media queries?

Bootstrap 3

Here are the selectors used in BS3, if you want to stay consistent:

@media(max-width:767px){}
@media(min-width:768px){}
@media(min-width:992px){}
@media(min-width:1200px){}

Note: FYI, this may be useful for debugging:

<span class="visible-xs">SIZE XS</span>
<span class="visible-sm">SIZE SM</span>
<span class="visible-md">SIZE MD</span>
<span class="visible-lg">SIZE LG</span>

Bootstrap 4

Here are the selectors used in BS4. There is no “lowest” setting in BS4 because “extra small” is the default. I.e. you would first code the XS size and then have these media overrides afterwards.

@media(min-width:576px){}
@media(min-width:768px){}
@media(min-width:992px){}
@media(min-width:1200px){}

Bootstrap 5

@media(min-width:576px){}
@media(min-width:768px){}
@media(min-width:992px){}
@media(min-width:1200px){}
@media(min-width:1400px){}

Update 2021-05-20: Info is still accurate as of versions 3.4.1, 4.6.0, 5.0.0.
