Sidebar Problems??

Okay basically, I’m trying to hide the sidebar on my website everywhere but my blog…(https://www.joellepoulos.com/blog/)

It is currently hidden everywhere but here: https://www.joellepoulos.com/portfolio/portraits/ (the code below hides it on this page though: https://www.joellepoulos.com/portfolio/art/)

So here it all the coding I have to hide the sidebar currently (custom CSS)

}
body.term-art div.site.site-with-sidebar, body.term-personal div.site.site-with-sidebar{
/*margin-left:-290px;*/
padding-left:25px;
}
#menu-item-1441 a {
pointer-events: none;
}

.single-fluxus_portfolio .site-with-sidebar {
padding-left: 0;
}

.page-template-template-portfolio-php .sidebar,
.single-fluxus_portfolio .sidebar {
display: none !important;
}

.page-template-template-portfolio-php .site-with-sidebar,
.single-fluxus_portfolio .site-with-sidebar {
padding-left: 15px;
}

I assume the reference to menu item 1441 is to my art page so how would I correctly find the menu item to my portraits page? I tried looking at the page source and 1441 doesn’t seem to exist either…. It’s not the end of the world if I don’t have the sidebar on my blog but it would be nice…
