>>6538029thank you. I'm not going to torture you more, but it did not worked for me :/ Maybe it is only my browser/configuration that won't cooperate with your css
I have found a way, though. added lines
-webkit-filter: blur(10px);
-moz-filter: blur(10px);
-o-filter: blur(10px);
-ms-filter: blur(10px);
filter: blur(10px);
