How to put the RSS Feed next to the Google Map API

Good morning, I'm trying to make a small HTML page with a Maps API and an RSS feed. However, I'm not able to put my RSS feed on the right side of the API. Can someone help me?

Here is the example of my page: HereisthecoderelatedtoRSSFeed:

<divid="widgetmain" style="text-align:left;overflow-y:auto;overflow-x:hidden;width:200px;background-color:#transparent; border:1px solid #333333;">
    <div id="rsswidget" style="height:500px;">
        <iframe src="http://us1.rssfeedwidget.com/getrss.php?time=1495402870570&amp;x=http%3A%2F%2Ffeeds.feedburner.com%2Fthr%2Freviews%2Fallreviews&amp;w=200&amp;h=500&amp;bc=333333&amp;bw=1&amp;bgc=transparent&amp;m=10&amp;it=true&amp;t=(default)&amp;tc=333333&amp;ts=15&amp;tb=transparent&amp;il=true&amp;lc=000003&amp;ls=14&amp;lb=true&amp;id=false&amp;dc=333333&amp;ds=14&amp;idt=true&amp;dtc=000000&amp;dts=12"border="0" hspace="0" vspace="0" frameborder="no" marginwidth="0" marginheight="0" style="border:0; padding:0; margin:0; width:200px; height:500px;" id="rssOutput">Reading RSS Feed ...
        </iframe>
    </div>
    <div style="text-align:right;margin-bottom:0;border-top:1px solid #333333;" id="widgetbottom">
        <span style="font-size:70%"><a href="http://www.rssfeedwidget.com">RSS feed</a>&nbsp;</span>
