I have a fresh Magento2 working and I am using Luma
as my template.
I want to add a costume image on the header that goes across the template, behind the logo.
Firebug directs me to:
page-header pub/static/frontend/Magento/luma/en_US/css/styles-l.css
I realize this is static location, so, I am not suppose to edit it.
where shouldI start? I just want edit the default luma theme
and I don't want add another costume theme. Since I am using the github
the templates are stored in frontend/Magento
Best Answer
go to
frontend/Magento/luma/web/css/source/_theme.less
override the css by simple adding these line
for adding the background in header
for adding the background image
