Css For Applying Correctly For A Bootstrap Box

I have created a html stuff which has a parent div named as row-one. row-one class is having height set to 40%. The html is rendering correctly and the parent height is applied to

Solution 1:

You have to give height to .portlet-layoutand .portlet-boundary. An elment with height: percentage value inherits from its parent so the parent element must have height value. However, you use the below rules:

Plunker

.portlet-layout,
.portlet-boundary
{
   height: 100%;
}

Solution 2:

you can try this one:

 style type="text/css">
    html,
    body {
      height: 100%;
      overflow: auto;
    }
    body {}
    .sidebar-nav {
      padding: 9px 0;
    }
    .row-one {
      height: 40%;
    }
    .row-one .child-fluid,
    .box {
      height: 100%;
    }
    .row-one .box {
      overflow: hidden;
    }
    .row-one .box-content {
      height: calc(100% - 57px);
      overflow-y: auto;
    }


   .portlet-layout,.portlet-boundary
     {
      height: 100%;
    }
</style>
