How to add buttons to the the header

Hi @kamillesaabre
check this thread for solution.

thanks

Also a Snippet

Thanks a lot. I am so thankful for your support.

I created new menu and then followed the instructions above.
But my button appears on the left side above the logo not on the right top. Also the font on the button is not showing correct color

Try:

.menu-item-3404 {
  float: right;
}
#menu-item-3404 > a {
  color: #000000; /* change black #000000 */
}

Thanks rdellconsulting for your help.
Worked nicely!
