Hi Eduard,

I do see that part of the code. But what should I do ?

This is the content of the css style:

.flowplayer { border: 1px solid #ff0000 !important; }

.flowplayer { margin: 0 auto 28px auto; display: block; }
.flowplayer.fixed-controls { margin: 0 auto 58px auto; display: block; }
.flowplayer.has-abloop { margin-bottom: 52px; }
.flowplayer.fixed-controls.has-abloop { margin-bottom: 82px; }
.flowplayer.has-caption, flowplayer.has-caption * { margin: 0 auto; }
.flowplayer .fp-controls, .flowplayer .fv-ab-loop, .fv-player-buttons a:active, .fv-player-buttons a { color: #eeeeee !important; background-color: #333333 !important; }
