Hello, @Dennis,
Simply go to the Dashboard >> XStore >> Theme Options >> Theme Custom CSS and then paste the below CSS code there and save settings.
::selection {
background: red;
color: white;
}
Note: In the above code the word “red” is the color you can see in the image: https://postimg.cc/Wq7c5WCS same as the white color.
