I’m sorry but I did not understand that.. (I’m not very good at codes etc)
Where can I find this? And what would I use it for?
What I’m looking for is for example I want the pages with ID 6, 7 and 8 to have 100% width. I can do that for only the page with ID 6 with the code lemu wrote. Now I’m looking for a way to re-write the code so that it works for multiple page-ID’s.
I.e this one so it works for 7 and 8 as well:
.page-id-6 .site-content{
width:100%;
}
