<title>MixItUp Pagination Demo - Responsive Pagination</title>
|
||||
|
||||
<!--
|
||||
Responsive pagination enables to define the initial pagination limit based on the
|
||||
viewport width and then make real time adjustments in reaction to resize events. This
|
||||
is crucial when we want to maintain a full final row in our grid when our CSS contains a
|
||||
mixer of odd and even column counts at different breakpoints.
