I'm using 100vh to center a div vertically with line-height. This site puts support for vh and vw at around 70%, is that a fair assessment? Would you recommend using viewport units when building a site? I know this is a bit subjective, I'm just looking for opinions from more experienced web developers than I.
EDIT: Thanks for the input everyone, I do want it to look good on mobile, so I guess I'll have to forgo vh.
use both CSS vh and jQuery, it's safer.
jQuery example:
var clientHeight = $( window ).height();
$('.element').css('height', clientHeight);
and CSS:
.element {height: 100vh;}
