how should I change this:
<body <?php body_class(); ?>>
<div class="wrapper">
<div id="header">
<!-- <a>" title="<?php echo esc_attr( get_bloginfo( 'name', 'display' ) ); ?>"><?php bloginfo( 'name' ); ?></a> -->
<html>
<head><title></title>
</head>
<a href="https://www.littlebusinesses.co.uk">
<div>
<span style="color:#FF6600;"><span style="font-size:34px;"><span style="font-family:georgia,serif;">Little <img src="https://littlebusinesses.co.uk/wp-content/uploads/2013/09/stock-photo-3310418-light-bulb-sketch.jpg" width="90" height="80" alt="Sell your start up" />Businesses</span></div>

</body> </a>
</html>
</div>
<div id="header-left"><?php wp_nav_menu( array( 'container_class' => 'menu', 'theme_location' => 'header-left', 'walker' => new Imbalance2_Walker_Nav_Menu(), 'depth' => 1 ) ); ?></div>
<div id="header-center"><?php wp_nav_menu( array( 'container_class' => 'menu', 'theme_location' => 'header-center', 'walker' => new Imbalance2_Walker_Nav_Menu(), 'depth' => 1 ) ); ?></div>
<div id="search">
<?php get_search_form(); ?>
<div id="header-right"><?php wp_nav_menu( array( 'container_class' => 'menu', 'theme_location' => 'header-right', 'walker' => new Imbalance2_Walker_Nav_Menu(), 'depth' => 1 ) ); ?></div>
</div>
<div class="clear"></div>
</div>
<div id="main">
