Menu
I like to make the header full width across the screen, the wrapper is 1052px and want to extend that while the logo and the menu stay in place.
Is there a way to expand the inner div to the full screen width in a responsive layout?
How can I fix this with css keeping in mind that "menu" is fixed at top and "full width" div must scroll normally? I think I cannot use absolute positioning. I hope it's clear, otherwise I'll try to improve the question.
here is the header.php code
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" <?php language_attributes(); ?>>
<head>
<meta http-equiv="Content-Type" content="<?php bloginfo('html_type'); ?>; charset=<?php bloginfo('charset'); ?>" />
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<link rel="pingback" href="<?php bloginfo('pingback_url'); ?>" />
<?php wp_head(); ?>
</head>
<body <?php body_class() ?>>
<div id="wrapper">
<div id="inner-wrap">
<div id="header" class="fullwidth">
<div id="logo">
<?php if (!option::get('misc_logo_path')) { echo "<h1>"; } ?>
<a href="<?php bloginfo('url'); ?>" title="<?php bloginfo('description'); ?>">
<?php if (!option::get('misc_logo_path')) { bloginfo('name'); } else { ?>
<img src="<?php echo ui::logo(); ?>" alt="<?php bloginfo('name'); ?>" />
<?php } ?>
</a>
<div id="header-amp"></div>
<?php if (!option::get('misc_logo_path')) { echo "</h1>"; } ?>
</div><!-- / #logo -->
<nav class="main-navbar" role="navigation">
<div class="navbar-header">
<?php if (has_nav_menu( 'primary' )) { ?>
<a class="navbar-toggle" href="#menu-main-slide">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</a>
<?php wp_nav_menu( array(
'container_id' => 'menu-main-slide',
'theme_location' => 'primary'
) );
} ?>
</div>
<div id="navbar-main">
<?php if (has_nav_menu( 'primary' )) {
wp_nav_menu( array(
'menu_class' => 'nav navbar-nav dropdown sf-menu',
'theme_location' => 'primary'
) );
} ?>
</div><!-- #navbar-main -->
</nav><!-- .navbar -->
<div class="clear"></div>
<div class="clear"></div>
</div><!-- / #header-->
<div id="main">

#inner-wrap{
width: 100vw; /* make it 100% of the viewport width (vw) */
margin-left: calc((100% - 100vw) / 2); /* then remove the gap to the left of the container with this equation */
}
The left margin equation is the key to get full width inside a container.
First, I get the total size of the container gap in a negative number (so the margin can be negative): 100% of the container - window size ( 100% - 100vw).
And last, I divide in half (the result above is for both left and right sides, so I just need the size of the left).
In summary, I'm making the inner-wrap width the same as the viewport width, then pull it to the left without using position:absolute or position:fixed, which would break the layout if you need more content below it.
You may need to adjust the parent if the 100% of the calc doesn't get the right size. position:relative can help.
