What text, specifically, do you want in header size? The tag can go anywhere in the body of the page. (It's like asking us where to put the underline and you show us a letter you're typing up. The answer is usually "wherever you want it".)

 

<div class="logo"><h1><a href="<?php echo home_url(); ?>" title="<?php bloginfo('title')?> - <?php bloginfo('description')?>"><img src="<?php echo $logo?>" alt="<?php bloginfo('title')?>" /></a></h1></div>

but make sure to define the text-indent

 

Usually H1 tag use as a heading tag, I think you should use H1 tag as your targeted keyword on the page. i.e. - "Apple Mobiles". H1 is most important part and it should be use only one time on the page.

 

You don't always need css.
