onclick header, open in top frame / new window?

PAGE IN QUESTION

Using…

<div id="header" onclick="window.location.href='https://famreflections.com/'" style="cursor: pointer;"></div>

	<div id="headerimg">
		<h1>
                   <a href="<?php echo get_option('home'); ?>/">
                     <?php bloginfo('name'); ?></a>
                 </h1>
		<div class="description">
                   <?php bloginfo('description'); ?>
		</div>
	</div>

…to make my header clickable. I would like it to open the link in the top frame and / or new window. Where would I add the code for that and what would the code be?

thank you
