}
The Steps to Take
1. First, we’ll comment out the sections that add the backstretch script.
2. Next we’ll add a new function to add the body background-image style, both in front-page.php.
3. And then we’ll add the positioning styles to style-front.css.
body.front-page {
background-attachment: fixed;
background-position: center center;
background-repeat: no-repeat;
-webkit-background-size: cover;
-moz-background-size: cover;
background-size: cover;
}
