Odd text positioning

[rades]

I can't understand why the text in the paragraph within #intro is positioning itself in such a way: http://www.physoc.org.uk/ (the 'Hello everyone....' text near the top of the page).I only have styling on #intro:\[code\]#intro { position:relative; top:160px; height:87px; background-color: rgba(255,255,255,0.6); border-radius: 10px; moz-border-radius: 10px; webkit-border-radius: 10px; font-size: 18px; font-weight:bold;}\[/code\], Thank you
