That’s how your site looks… posts on the left, wide sidebar on the right.
See https://i.imgur.com/JKT2UQw.png

I would like to move the blog posts over more to the left to take up more of the website then make my sidebar wider.
Start by making the whole page wider
@media only screen and (min-width: 800px) {
.site-container {
max-width: 1400px;
}
}
