Hier mein CSS für das Firefox-Feedreader-Addon "Brief". Das Style rendert die Listenansicht sehr kompakt.

/* Don't show authors of items */ /*
.article-authors {
    display: none;
}
*/

/* Increase the font size */ 
.article-content {
 font-size: 8pt; !important;
}

#feed-image {
	margin: 0 0px 0px;
	max-width:400px;
	max-height:100px;
}

.article-title-link {
    font-size: 7.5pt !important;
}

.article-container[collapsed] .collapsed-article-subheader {
    color: grey;
    padding: 0 0px;
}

.article-subheader, .collapsed-article-subheader {
    font-family: "Lucida Grande", Verdana, sans-serif;
    font-size: 7pt;
    line-height: 12pt;
    /* Make the height the same for both
        Lucida and Verdana */
}
.article-container[collapsed] {
    min-height: 20pt;
}
.article-container[collapsed] .article-date,
.article-container[collapsed] .feed-name,
.article-container[starred] .article-date,
.article-container[starred] .feed-name{
    float: right;
}
.article-container[collapsed] .article-date {
	
}
/* Crop feed names longer than 170px */
.article-container[collapsed] .feed-name {
    max-width: 170px;
    overflow: hidden;
    padding-right:0.5em;
    color:black;
}

.article-container[collapsed] .article-controls {
    font-size: 6pt;
    margin: -3px 0px 0px 5px;
}
