Thank you both. @joyously thank you – I posted the question to that forum. @t-p thank you – I know zero about code, a custom CSS editor, etc. but I did see at the bottom of the customize appearance tab there was something called “additional CSS” as you mentioned. I copied and pasted:
#site-header {
background-image: url(‘https://www.medicalpracticegeek.com/wp-content/uploads/2018/09/Untitled_Panorama1-copy.jpg’);
background-size: 100%;
}
into the lines at the bottom and the picture disappeared/went black. Not sure if I am supposed to enter all of this in its entirely or just add the “background-size: 100%” somewhere. Again, zero background here or coding knowledge. I’m sure this looks like such a childish issue, but I thank you for your help. Any other thoughts would be appreciated, but I’ll look into the child theme you mentioned (though that looks daunting as well).
