icon before every title

use:

article.page .format-icon:before {
content: none !important;
}

p.s.
Look that you have wrong stuff in your custom css:

// NAVBAR WRAPPER //
add_filter('tc_navbar_display', 'rdc_navbar_display');
function rdc_navbar_display($output) {
return preg_replace('|navbar-wrapper clearfix span9|', 'navbar-wrapper clearfix', $output);
}

// LOGO //
// center the logo
add_filter('tc_logo_text_display', 'rdc_custom_center_brand');
add_filter('tc_logo_img_display', 'rdc_custom_center_brand');
function rdc_custom_center_brand($output) {
return preg_replace('|span3|', 'span12', $output);
}

// TAGLINE //
// center the Tagline
add_filter('tc_tagline_display', 'rdc_tagline_display');
function rdc_tagline_display($output) {
return preg_replace('|span7|', 'span12', $output);
}

// SOCIAL ICONS //
// center the output of tc_social_in_header:
add_filter('tc_social_in_header', 'rdc_social_in_header');
function rdc_social_in_header($output) {
return preg_replace('|span5|', 'span12', $output);
}

php ode should stay in your child theme functions.php if you need it.. but never in a css.

you have this:

@media (max-width: 979px){
    .round-div, .span4 .widget-front .round-div {
        border-color: #1a1110;
    }

article.page .format-icon:before {
content: none !important;
}

You didn’t close the bracket for the media query. Make that become this:

article.page .format-icon:before {
content: none !important;
}

@media (max-width: 979px){
    .round-div, .span4 .widget-front .round-div {
        border-color: #1a1110;
    }
}

Hope this helps.
