I want to use a second domain for my mobile web site which will be a clone of my desktop web site with some graphics changes.
I need to do this because my desktop web site uses MP4 in background and mobiles do not handle this so I want to copy the site and change the mp4s into a simple slider.
So will I need a complete new x theme/cornerstone to do this??
Yes, a different domain is a different license.
You can always create a " Mobile Theme " for the web site and mobile users will be redirected to that, so no extar stuff required
how can i have different graphics on a mobile site?
As explained above
You can use media queries or wp_is_mobile() wordpress function.
Depends on what you want to do and how are your skills. Always can help if you want further and do not know how!
yes please guide me moreā¦
I suspect the wp_is_mobile() is the easy part but I am up for the challenge!
Please check out the WordPress codex and if need more help, I can help yes!
