Fixed Css-bug

It is because of both. In the gallery style, it has float: left property on the username element and in your style it has display: inline on the blockquote, article element. This combination makes the above issue on Firefox and probably on older version of IE as well.

So you have two choices: Remove float on gallery or display on your style. I suggest you stick with the first choice which will not affect the rest parts of your site.

Please do this in following templates: sonnb_xengallery_photo_view.css, sonnb_xengallery_photo_view_overlay.css

HTML:

.commentContainer .commentInfo .commentContent .username.poster {
    float: left; <--- Remove this line
        margin-right: 5px;
}

 

This is now removed by default.
