Prestashop - How to add or remove space between footer and page content

I would like to ask you some help about managing the space between the footer and the page content in Prestashop.

My Prestashop version is 1.6.1.17.

The website is www.backlabel.com.

I have the following problem:

On the home page, the space between the embedded video and the footer is greater that I want to be and would like to reduce it. However I cannot identify, even through the Inspect Function of Chrome browser, the part that I should modify and I'm lost.
I know that in asylum.css there is a #footer part that has some specifications, however I already have removed its margin, and that space still remains. See image below for more clarification. Distance between embedded video and footer highlighted in red
On the login page, having removed the margin from the footer, subsequentially it remains very attached to the content while instead I would like to add a space and to make the footer stay on the bottom. See image for more clarification.

Can anyone help?

Thank you in advance

Solution

For the space on between your video and the footer, this css code will solve your issue :

body .cms_24 .wht_bg{
  top:0;
}

For your 3rd point (login page), use this JS code to keep your footer always at the bottom. Tested and works great.

var docHeight = $(window).height();
var footerHeight = $('#footer').height();
var footerTop = $('#footer').position().top + footerHeight;
if (footerTop < docHeight)
    $('#footer').css('margin-top', (docHeight - footerTop) + 'px');

cheers :)
