Linking WordPress Header Image to Page – HELP!

Hello –

I am new to WordPress and am having a very hard time linking a header image on my site to a page on the blog. The header image is added in the custom CSS and all of the different code I’ve tried isn’t working – so I thought I’d ask the experts! ??

My site is: complianceandethics.org and I’m trying to link the image at the top to another page on the site. The custom CSS starts out:

.site-header {

All of the code that I’ve seen and tried looks like this:

<div id=”header” onclick=”location.href=’https://siteaddress/&#8217;;” style=”cursor: pointer;”>

There isn’t anywhere that I can find where the code is styled that way.

I’m using eleven40 Pro Theme.

My CSS skills are not great, and I’m learning as I go, so any help is much appreciated!
