The text? That's in the "Change Content" bit, not in the code. Unless you're on about editing the fonts and such, then that's this bit here:
HTML Code:
/* Entries */
.entry {
font-size:1.4em;
color:#589ac2;
padding:5px 10px;
text-align:center;
line-height:1.75em;
}
.entry-title {
font-size:3em;
color:#36494d;
font-weight:bold;
letter-spacing:-1px;
style:Trebuchet MS;
}
.date {
font-size:0.9em;
color:#bedde3;
cursor:default;
letter-spacing:1px;
}
.comments {
margin-top:-1em;
}
.comments a {
color:#6CC7DC;
background:url(images/icon-comment.png) no-repeat 0px 2px;
padding-left:20px;
padding-right:2px;
}
.comments a:hover {
color:#B4C835;
}
