Changing Font Family throughout whole Enfold

Hi.
I wish to change the font family throughout the entire Enfold theme, and some of the places i have had succes with it.
But especially in menues and footer I have big troubles to make the changes.
I have this in my quick css :

#fwcs .container { width: 100% !important; max-width: 100%; padding: 0; margin: 0; }

#top .av-main-nav ul a {
padding: 2px 15px;
}

add_filter(‘avf_template_builder_content’, ‘avia_add_social_toolbar_template_builder’, 10, 1);
function avia_add_social_toolbar_template_builder($content = “”)
{
$content .= avia_social_share_links(array(), false, ”, false);
$content .= ”;
return $content;
}
strong.logo a img {
padding-top: 18px !important;
}

.header-scrolled strong.logo a img {
padding-top: 5px !important;
}

.main_color table caption, .main_color tr:nth-child(even), .main_color .pricing-table>li:nth-child(even) { color: inherit; }
tr:first-child th, tr:first-child td,tr th:first-child, tr td:first-child,td { border: none !important; }

add_filter( ‘avf_google_heading_font’, ‘avia_add_heading_font’);
function avia_add_heading_font($fonts)
{
$fonts[‘Titillium+Web’] = ‘Titillium+Web’;
return $fonts;
}

And this in my functions.php :

<?php

/*
* Add your own functions here. You can also copy some of the theme functions into this file.
* WordPress will use those functions instead of the original functions then.
*/
add_filter( ‘avf_google_heading_font’, ‘avia_add_heading_font’);
function avia_add_heading_font($fonts)
{
$fonts[‘Titillium+Web’] = ‘Titillium+Web’;
return $fonts;
}

add_filter( ‘avf_google_content_font’, ‘avia_add_content_font’);
function avia_add_content_font($fonts)
{
$fonts[‘Titillium+Web’] = ‘Titillium+Web’;
return $fonts;
}

As I have understood, this should be enougt to change the font family throughout the theme ?
