Issue with quick css

My website was running well.
I just updated my home page and some code on the quick css updated by itself (i do not change anything here).
It puts wrong value as you can see with { and this } :

time.slide-meta-time {
display: none!important;
}
.av-inner-tab-title {
font-size: 15px;
font-weight: bold;
}
#top .av_header_glassy.av_header_transparency #header_main {
background-color: rgba(255,255,255,0.8);
}
/* Sticky header on mobile */
@media only screen and (max-width: 767px) {
.responsive #top #main {
/* Margin top value should be equal to header height*/
margin-top: 0px;
}
.responsive #top #wrap_all #header {
position: fixed;
}
}

——————————————————
So i tried to clean up as below :
——————————————————-
time.slide-meta-time {
display: none!important;
}
.av-inner-tab-title {
font-size: 15px;
font-weight: bold;
}
#top .av_header_glassy.av_header_transparency #header_main {
background-color: rgba(255,255,255,0.8);
}
/* Sticky header on mobile */
@media only screen and (max-width: 767px) {
.responsive #top #main
}
/* Margin top value should be equal to header height*/
margin-top: 0px;
}
.responsive #top #wrap_all #header {
position: fixed;
}

1-Can you confirm the codes are correct?
2-but i still have issue because H2 are now in Bold and do not use the default type family
3-I tryed to erase all quick CSS but it doesn’t solv anything.
4-AND the homepage don’t display anymore on backend : https://thaigourmet.fr/enfold.png
