I searched further on the forums and found this:
.fl-builder .entry-header,
.fl-builder .synved-social-container,
.fl-builder footer.entry-meta,
.fl-builder .comments-area,
.fl-builder.archive .container.grid-container,
.fl-builder.blog.container.grid-container {
max-width: 1980px;
}I then still had padding all round, so I then used developer tools to add this:
.separate-containers .inside-article, .separate-containers .comments-area, .separate-containers .page-header, .separate-containers .paging-navigation, .one-container .site-content {
padding: 0px 0px 0px 0px;
}
Not sure if this is all required, but for now it seems to work OK
Thanks, Dave
