I came across this issue just a short while ago – a client had a header that they wanted to use on a WordPress website, but it didn’t fit the usual size constraints so when I added it the darn thing was shunted over to the left. Not good!
So I found a nifty article that helped me sort it all out, just a quick and simple matter of updating some css in the child theme:
.header-image { margin-left: auto; margin-right: auto; display:block; }
Voila!
Thank you…I’ve been searching for this answer for days! Thank you, thank you, thank you.
Glad I could help!
Pure genius, i have been wrestling with this problem for a while, thankyou
