You can take a look at this topic. Or you can just buy this addon. It works fine.

@dave3 I try this:

.block.block--category.block--category14{
    @media (min-width: 1100px){
    .block-body{
        display: grid;
    grid-template-rows: auto;
    grid-template-columns: 50% auto;
        }
        
    }
    
}

And it shows perfect but i only want to display grip in two specific nodes. I don't know how to put this two nodes only in grip
.node.node--id25
.node.node--id26
