In the following CSS, font-size normal is not valid.

.bookreview .label2 { font-weight: bold; font-size: normal; float: left; padding-right: 5px; }
.bookreview .content2 { font-weight: normal; font-size: normal; }

Replace with medium:

.bookreview .label2 { font-weight: bold; font-size: medium; float: left; padding-right: 5px; }
.bookreview .content2 { font-weight: normal; font-size: medium; }
