text drag color & Touch mark area on mobile

Site URL: https://seonto.kr

1. How can I change the text drag color on mobile?
I add this code on custom CSS page. PC mode is works, but not on the mobile..

	::selection
		{
			color : #82aaaa ! important ;
			background : rgba(155, 195, 195, 0.15) ! important ;
		}


		@media screen and (max-width: 767px)
			{
				::selection
				{
				color : #82aaaa ! important ;
				background : rgba(155, 195, 195, 0.15) ! important ;
				}
			}

2. When I touch some image or title on mobile website, the touch mark area (gray block) is shows on. Can I hide or remove it on all web site on mobile? Thanks :)

::selection works on most browsers, but doesn't work on iOS mobile. From a quick bit of research, it doesn't look like there's a way to change this on iOS mobile.

Thanks a lot! Then there's no way to remove the touch mark area too?
