[Theme:Restaurateur] Logo next to slider in header

Does anyone know how to do this? I have tried to put them next to each other with float but that doesnt work in PHP so i am having a bit of a trouble now. I removed the header logo temporary and put it in the homepage but i need to change it back so both the logo and slider are on top.. how do i do this?

My website Matuya

please help me!

I still have the logo code here if it helps a bit.

<?php if ( get_theme_mod( 'restaurateur_logo' ) ) : ?>
            <div id="site-logo"><a href="<?php echo esc_url( home_url( '/' ) ); ?>" title="<?php echo esc_attr( get_bloginfo( 'name', 'display' ) ); ?>" rel="home"><img src="<?php echo esc_url( get_theme_mod( 'restaurateur_logo' ) ); ?>" alt="<?php echo esc_attr( get_bloginfo( 'name', 'display' ) ); ?>" /></a></div>

 <?php else : ?>
			<div id="site-title"><a href="<?php echo esc_url( home_url( '/' ) ); ?>" title="<?php echo esc_attr( get_bloginfo( 'name', 'display' ) ); ?>" rel="home"><?php bloginfo( 'name' ); ?></a></div>
            <?php endif; ?>
		</div>
