.htaccess - Linking from a subfolder back to the root folder index.html file -

i having trouble linking subfolder index file root folder index file.

i have logo in nav bar of example.com/blog have link example.com

i have tested various linking options logo image including

<a href="../index.html"> <a href="http://www.example.com"> <a href="../">

and none of them seem work. logo image continues link example.com/blog/index.html

the strange thing if right click on image , select open in new window/tab, load example.com fine.

i @ complete loss.

could related .htaccess file?

additional info

i added "home" text link nav bar using below syntax , works perfectly.

<a href="http://www.example.com">home</a>

the image reason not link rootfolder index.html file using same syntax. keeps loading http://www.example.com/blog/index.html

try using javascript redirect

function home() {    window.location.replace("http://example.com");    }

<button onclick="home()">hi</button>
