I am trying to figure out how I can stretch my slider image to the full-page width, but have it also be responsive. I am running on Wordpress and I'm not opposed to using Javascript if necessary. Here is the site: http://cmattayers.com/b2bu/
This is my original mockup, if that helps: https://i.stack.imgur.com/jaOcW.jpg
Pull the slider div at the end but inside just before last
</div>
of<div class="navbar-header">
it may be found in yourheader.php
if you use a shortcode like[yourslidershortcode]
in your page content you have to modify it before post into direct themeheader.php
put<?php echo do_shortcode( '[yourslidershortcode]' ); ?>
I found the in the site you mentioned
If the slider show only on home page use below code instead of above
