I have a simple Chrome extension that uses the content script feature to modify a website. More specifically, the background-image
of said website.
For some reason I can't seem to be able to use local images, even though they are packed in the extension.
body {
background: #000 url('image.jpg') !important;
background-repeat: repeat !important;
}
That's it, the simplest CSS... but it won't work. The browser doesn't load the image.
Chrome has i18n support that provides the ability to reference your extension in your CSS. I keep my images in an image folder in the extension, so reference assets in the CSS like so:
background-image:url('chrome-extension://__MSG_@@extension_id__/images/main.png');
