Hi Jörg!

Das ist simples CSS und z.B. über Firefox und Web-Entwickler kannst du jede Class oder ID herausfinden.

Probiere mal das in deiner Qick-CSS: #socket {font-size: 20px!important;}
Schriftgröße 20px ist nur damit du mal den Unterschied siehst.

if this is all your Quick CSS – then why is clear for above reasons.
there are some closing brackets missing – each opening bracket must have a closing bracket.

@media only screen and (max-width: 767px) {
	.av_textblock_section .avia_textblock p * {
	font-size: 12px !important
	}
}
@media only screen and (max-width: 767px) {
	.responsive #scroll-top-link {
	display: block!important;
	}
}

But because the media query is the same – you can combine them to:

@media only screen and (max-width: 767px) {
	.av_textblock_section .avia_textblock p * {
	font-size: 12px !important
	}
	.responsive #scroll-top-link {
	display: block!important;
	}
}

Edit

Actually I think as someone who wanted to help you with the solution I have a certain right to know if and how you solved the problem.
Unfortunately the topic was already closed – but maybe you’ll come back to read this.

it sound for me – as if you entered a css rule in quick css that is not well formated.
A missing closing bracket e.g. on a media-query rule could be happen easily.
If you can post your quick css – we can see what happens

My guess is based on the fact that on Enfold these setting below are just behind your quick css rules
if there is on top a missing closing bracket – every rule after that has no effect.

.container {width:100%;} .container .av-content-small.units {width:75%; }
			
	 .responsive .boxed#top , .responsive.html_boxed.html_header_sticky #header, 
	 .responsive.html_boxed.html_header_transparency #header{ width: 1310px; max-width:90%; }
	 .responsive .container{ max-width: 1310px; }
			
#top #wrap_all .av-main-nav ul > li > a, #top #wrap_all .avia_mega_div, #top #wrap_all .avia_mega_div ul, #top #wrap_all .av-main-nav ul ul{color:#404040;background-color:#cfcfcf;font-size:14px;}
#top #header .av-main-nav > li > a{color:#000000;}
#top #header .av-main-nav > li > a .avia-menu-text, #top #header .av-main-nav > li > a .avia-menu-subtext{color: #000000;}

and you see that jordans rule above is part of this enfold options css under the quick css.

if you had a top menu then the activation is done and that little snippet of avia_meta_header is unnecessary:
this you can erase : add_filter( 'avf_execute_avia_meta_header', '__return_true', 10, 1);

the css will depend on the position of top menu – this here is for left position:

#header_meta .av-rotator-container {
    font-size: 24px !important;
    position: relative;
    left: 50%;
    float: left !important;
    transform: translateX(-50%);
    top: -10px;
}

.av_secondary_left .sub_menu {
  width: 80%;
}

#header_meta span {
    font-size: 30px;
}

there is a hook if the sub-menu is present.
– but if we don’t want sub-menu on top we can activate it nevertheless via filter:

add_filter( 'avf_execute_avia_meta_header', '__return_true', 10, 1);
add_action('avia_meta_header', function() {
if(is_page(3)){
echo do_shortcode("[ av_headline_rotator before_rotating='' after_rotating='' interval='5' animation='' margin='' margin_sync='true' tag='h2' size='36' align='center' custom_title='' av-medium-font-size-title='' av-small-font-size-title='' av-mini-font-size-title='' alb_description='' id='' custom_class='' av_uid='av-k1gw6wo0' admin_preview_bg='']
	[ av_rotator_item title='today we offer abc' link='' linktarget='' custom_title='' av_uid='av-it587']
	[ av_rotator_item title='but the whole week it is' link='' linktarget='' custom_title='' av_uid='av-egknj']
	[ av_rotator_item title='⇒ another line to present' link='' linktarget='' custom_title='' av_uid='av-6u493']
[ /av_headline_rotator]");
};
});

a little css to position it:

#header_meta .sub_menu {
    font-size: 24px !important;
    position: relative;
    left: 50%;
    float: left !important;
    transform: translateX(-50%);
    top: 0;
}

#header_meta span {
    font-size: 30px;
}
