Added widget above content, pushing right sidebar down

I’m trying to add some text above the center content on the home page, and want the two sidebars (left & right) to be unaffected, i.e. float to the top. However, it is pushing the right sidebar down.

I’ve styled it like so:

#sidebar-5 {
	float: left;
	margin: 0 auto;
	width: 570px;
	padding: 0 0 10px 0;
}

and the PHP for the home page has divs added before the Content area for both the left sidebar and the widget I’m adding like so:

<div id="sidebar-3">
	<?php if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar('sidebar-3') ) ?>
</div>

<div id="sidebar-5">
	<?php if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar('sidebar-5') ) ?>
</div>

[please remember to mark any posted code – https://codex.www.ads-software.com/Forum_Welcome#Posting_Code ]

Should I somehow combine those divs? Or what?

Thanks for any help!
