(OPTIONAL) And if you want the image to stay fixed go to css_additional.css template of your theme and find the following css-rules –
body {
background: {vb:stylevar quarto_background_image};
background-color: {vb:stylevar body_background.color};
/*background-size: 100% auto;*/
/*background-attachment: fixed;*/
}
Now just uncomment background-attachment rule –
body {
background: {vb:stylevar quarto_background_image};
background-color: {vb:stylevar body_background.color};
/*background-size: 100% auto;*/
background-attachment: fixed;
}
You can also uncomment the background-size rule. In this case your image (if you using a wide photo) will always be 100% wide. But don’t use the background-size rule with tiling images.
