Hi Charles,
You can utilize Topbar as well for this type of addition as it will accept HTML inside Topbar content area. You can enable Topbar by head over to X -> Theme Options -> Header -> Miscellaneous area.
So it should display as follows.
If you’re using WPML, you can refer to the following post (https://theme.co/apex/forum/t/wpml-language-switcher-position-at-topbar/52894/2?u=mldarshana) or you can implement your language switcher code as you prefer.
To change background color of your Topbar, you can add the following CSS rule into your X -> Theme Options -> CSS area and change the color values accordingly.
.x-topbar {
background-color: rgba(0,0,0,0.45);
}
Please note that custom coding is outside the scope of our support. Issues that might arise from the use of custom code and further enhancements should be directed to a third party developer.
Thanks!
