You would have to adjust each div section that is 1152px since they are all separate of each other on the homepage. To change the width on the homepage only, you can add “.home” to any div/class that you change, and it won’t affect other pages.
For example, the #header is 1152px, so you would need to add this to change the #header on just the homepage –
.home #header {
width: 600px;
}
You can take a look at all of the other div’s on your homepage and do the same each one that is 1152px.
