3delamadrugada on "Erase blank spaces, what code can I use?"

hello,

I just want to erase the blank spaces betwen my slideshare and the sentence in the botom of it.
sometimes it´s with no space at all, really close to it, but right now there is white space that I would really like to erase.

what code can I use to do that? (I know for adding spaces you can use
, but what for erasing them?)

this is the page:

and this is the code I use in it:

<p style="text-align: center;">[gigya width="470" height="670" src="http://static.slidesharecdn.com/swf/doc_player.swf?doc=dossierprensaelcorazonlaboca-100812133957-phpapp01&stripped_title=dossier-prensa-el-corazonla-boca" quality="high" flashvars="gig_lt=1281966567880&gig_pt=1281967114967&gig_g=2&gig_n=wordpress" wmode="tranparent" allowfullscreen="true" ]</p>
