Is it possible to make an element's width the full width of the screen instead of the parent's width? If so, how can this be achieved?
<header>
<nav class="navbar navbar-inverse navbar-fixed-top" data-tap-toggle="false" role="navigation">
<div class="container-fluid">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#"><img id="12" src="img/logo-3.jpg" alt="logo"></a>
</div>
<!-- Collect the nav links, forms, and other content for toggling -->
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav" id="menu">
<li><a href="#" class="drop">ENTERTAINMENT</a><!-- Begin 3 columns Item -->
<div class="dropdown_3columns"><!-- Begin 3 columns container -->
<div class="col_1">

<a href="2.html"><h2>2</h2></a>
