#media only screen and (max-width: 500px) {
.top-bar-section ul {
margin-top: 15px;
}
}
#media only screen and (min-width: 300px) and (max-width: 500px) {
.widget-area {
display: none;
}
.stat {
margin-bottom: 30px;
}
.clients-style-2 .slides li .client-logo {
margin-bottom: 5px;
}
#clients .slides li .client-logo {
margin-bottom: 5px;
}
#icategories li {
margin-bottom: 10px;
}
}

Answer 1

You have a YouTube video in an iframe, and that iframe has a hard coded width of 500px, so this will be a problem on narrower viewports.
CSS Tricks has one solution to this, jQuery below. There are other solutions for responsive iframes, I like that this is a simple drop fix which doesn't require any changes to your HTML, and also that it resizes both the width and the height of your video.
Hope this helps!
// By Chris Coyier & tweaked by Mathias Bynens
$(function() {
// Find all YouTube videos
var $allVideos = $("iframe[src^='http://www.youtube.com']"),
// The element that is fluid width
$fluidEl = $("body");
// Figure out and save aspect ratio for each video
$allVideos.each(function() {
$(this)
.data('aspectRatio', this.height / this.width)
// and remove the hard coded width/height
.removeAttr('height')
.removeAttr('width');
});
// When the window is resized
// (You'll probably want to debounce this)
$(window).resize(function() {
var newWidth = $fluidEl.width();
// Resize all videos according to their own aspect ratio
$allVideos.each(function() {
var $el = $(this);
$el
.width(newWidth)
.height(newWidth * $el.data('aspectRatio'));
});
// Kick off one resize to fix all videos on page load
}).resize();
});
