Hogy lehet megoldani, hogy csak a háttér legyen átlátszó, a képek táblázatok, stb. ne? (Töbi lent)

A css fájl:

body{

font-weight:900;

font-stretch:condensed;

font-style:obliqe;

font-size:large;

background:url("voyhat.jpeg");

background-size:1920px 1080px;

background-repeat:no-repeat;

background-attachment:fixed;

}

#container{

background-image:-moz-linear-gradient(170deg,#40E0D0, #00FF7F,);

background-image:-webkit-linear-gradient(170deg,#40E0D0, #00FF7F);

background-image:linear-gradient(170deg,#40E0D0, #00FF7F);

color: black;

width: 1000px;

height: 5000px;

border: solid 3px black;

opacity:0.8;

}

h1{

color:Red;

font-family:"Lucida Console",Monaco,monoscape;

font-weight:bold;

}
