Can you set a border opacity in CSS?
...-transparent. The best way to make the border semi-transparent is with the rgba color format. For example, this would give a red border with 50% opacity:
div {
border: 1px solid rgba(255, 0, 0, .5);
-webkit-background-clip: padding-box; /* for Safari */
background-clip: padding-box; /* ...
Making text background transparent but not text itself

Don't use opacity for this, set the background to an RGBA-value instead to only make the background semi-transparent. In your case it would be like this.
.content {
padding:20px;
width:710px;
position:relative;
background: rgb(204, 204, 204); /* Fallback for ol...
