There is some confusion surrounding the issue below:
<div class="container">
<div class="row">
<div class="group">
<a>
<div class="col-lg-3 full-h"></div>
</a>
<a>
<div class="col-lg-3 full-h"></div>
</a>
<a>
<div class="col-lg-3 full-h"></div>
</a>
</div>
</div>
</div>
and
html, body { height: 100%; }
.full-h {
height: 50%;
}
I am questioning whether setting the height of container, row and group to height: 100% is necessary for the proper application of full-h. Without this setting, it doesn't seem to work correctly.
