It did not work.

something in my childtheme or in spakles theme is blocking some of my changes

here is my custome css

/* Custom CSS*/  

@media (max-width: 1000px){
.main-navigation ul.menu>li.site-mobile-menu-logo{
	width: 103.5%;
	text-align: center;
	padding: 1px 11px 11px 1px;

}
.main-navigation ul.menu > li.site-mobile-menu-toggle{
	position: absolute; 
	background: transparent;
	left: 0px;
	z-index: 1;
}
.main-navigation ul.menu>li.menu-item-gsearch{
	position: absolute;
	right: -5px;
	z-index: 1;
}

html .site-banner .site-logo img{
	width: auto;
	height: 40px;
	max-width: 100%;
	padding-bottom: 3px;
}

.site-content[role="main"]>article.post {
	padding-top: 30px;
	padding-bottom: 15px;
}

.single-post .site-content article h1.entry-title{
	text-align: center;
}

add_filter( 'post_thumbnail_size', 'filter_post_thumbnail_size_jan132014' );
function filter_post_thumbnail_size_jan132014( $size ){
	if( wp_is_mobile() )
		$size = 'medium';
	return $size;
}

.site-hero .with-cmt{
	display:none !important;
}

html body .entry-title,
html body .post-title{ text-align:left !important; 

}

html.site-hero .hero-brick:hover .entry-thumbnail img{
transform: scale(1);
-webkit-transform: scale(1);
-moz-transform: scale(1);
-ms-transform: scale(1);
}

.entry-header .entry-meta .avatar{ display:none;}

@media (max-width: 991px){

	.single-post .site-content article h1.entry-title {
		font-size: 35px;
	}
}

}
}

I was able to find the solution to my problem. Apparently W3TC plugin has an error where the option “purge CDN cache completely” doesn’t work, so I had to go to my MAXCDN account and do it from there.

btw the code you gave me works, but not on desktops.

Its okay now since I am not using the author picture in the post meta info.

Thank you guys!
