` for ALL pages except the blog page and posts? which will in turn only require me to make a cutom template for the blog page which the above link describes…
please keep in mind that I am new to blade/sage 9 and have only previously used the old roots theme and I have read up on blade and watched screencasts etc but cannot seem to figure this out.
Hope all that makes sense… trying not to repeat my self in code and keep everything as clean as possible…

You could most easily achieve this with Sass:
```
.wrap {
@extend .container;
.blog &,
.post-single & {
@extend .container-fluid;
}
}
```
(Or something like that. That’s untested.)
Or with Controller by adding a variable of classes that you fill conditionally:
```
```

@MWDelaney thank you for your quick reply.
Seems like the controller method would be simpler? as I am trying to keep the css as lean as possible.
however can you please elaborate?

newbie @ both sage9/blade/controllers and no idea on how to implement that. I read up on: [GitHub - soberwp/controller: Composer package to enable a controller when using Blade with Sage 9](https://github.com/soberwp/controller#overview) and info on this post here:
[https://discourse.roots.io/t/how-to-create-a-controller-file-for-a-custom-template-page-in-sage-9/11833/4](https://discourse.roots.io/t/how-to-create-a-controller-file-for-a-custom-template-page-in-sage-9/11833/4)
I tried but all i get is broken pages :worried:

Honestly, I’d just set the container class full width by default and fixed width for blog/single pages in css. Much simpler than setting up these named specific classes all the time. And one could argue these bootstrap class names go against the concept of separating style and content.

In `app/controllers/app.php` add the following function to the class:
```
public function containerclasses() {
return “container-fluid”;
}
```
In `app/controllers` create `blog.php` and make its contents:

**Thanks guys** for your input. Much appreciated.
I have played around with this for a few days now and cannot get my head around it. The code works with no errors but the container class isn’t reflected as I wanted. Most definitely because I’m new to blade and probably didn’t add in additional stuff to control it all (and when I did I just got errors galore).
I just went ahead and created a full-width template instead which I now manually select in pages that require the full-width container. It’s less DRY but working!
