If you want to hide the horizontal scroll bar you can apply some css as well. However that's probably happening because you have a smaller screen width. You could also optionally use some css to make the page wider, I think flarum by default has 1100px width for large screens - on my forum I increased that slightly to 1200px.
.FlarumBlog-Article-Post .Post-body{
overflow-x: hidden;
}
Larger width page
@media (min-width: 1200px) {
.container {
width:1200px !important;
}
}
