Update meines 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;
}

.article-title-link {
    font-size: 8pt !important;
}

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

.article-controls {
   font-size: 8pt !important;  
}


.collapsed-article-subheader,
.collapsed-article-subheader .article-date,
.collapsed-article-subheader .feed-name{
   float: right;
   display: inline;
}

.article-container[collapsed] {
    min-height: 20pt;
}

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