how to add html code

Hello,

Please, help with how I could add html code to a page.
E.g., I want to add a div with a text and link between logo and card. I could see it using Firebug in Firefox as below:

<div id="gkPageTop" class="gkMain ">
<h1 id="gkLogo">
a custom <div> could go here.
<div id="gkCartBtn">

so I could add between it something as <div style="float: left; padding-left 60px;"> ... </div>.
I also could see it's working there but where I could go in the Template to do it.

Thanks

The easiest way is to modify code in logo area, you will find this area in template/layout/blocks/logo.php or in layout/default.php file.
