Isuues with CSS

Hello,

I added some this CSS to our site which was working fine yesterday, but checked the site today but none of its appearing! I have deleted my cache but still no luck. The CSS I added was:

#menu-item-search {display:none;}

.gf_progressbar [display:none;}

#top .av-main-nav > li > a { letter-spacing: 0.2em !important; }

.avia-button.avia-size-large { font-size: 17px; }

.avia-caption-title { text-transform: none !important; }

span.hr-inner {
border-color: #3a3a50 !important;
}

.socket-background {
height: 140px;
}

body #gform_wrapper_1
{
Font-family: Poppins ;
}

#top label {
font-weight: normal;
font-size: 18px;
}

Thank you in advance! We love your theme! :)
