I use this code in the style.css of Mantle. .site-header { background-image: url('http://www.mysite.com/v2/wp-content/uploads/2015/06/TEST-Home-Page-V2.png'); height: 299px; } But, when I use the mobile version the png is too big (1400X300). How i can resize the background png size auto, if i use an iphone or an ipda ? Thank you….

You’re better off applying a different image suited for mobile when on smaller devices. For example: @media (max-width:767px) { .site-header { background-image: url('URL TO MOBILE IMAGE'); } } Also, since you’re using a child theme we release updates to, I suggest you use methods #2 or #3 to add your CSS: http://generatepress.com/knowledgebase/adding-css/ Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic.
