I know it’s not a query on the performance of GeneratePress, but there goes …
The following code works perfectly on pages without sidebar:
.no-sidebar .inside-article > * {
max-width: 700px;
margin-left: auto;
margin-right: auto;
}
But I use WPSP to display the pages of the categories and, as it does not have a sidebar, it also affects them.
The question is: Can this css be applied only to specific pages? Maybe with the page ID? Or do I forget the subject?
