Yes, you can create a separate layout for that page where you could
implement some sort of mechanism to change the size of the container.
That would probably be the best solution from a performance
standpoint, and it can be set in the view.yml. But that still leaves
the question of how to update the dynamic containers' style.
Also, I believe slots are cached (don't quote me on that though), and
I would stay away from the attribute method. Say you need to change
the name of the param for some reason, it would be a maintenance
nightmare
I was thinking, you could also create temporary stylesheets and save
them to create your own little css file cache, something that have the
width value in the name so you could reuse them. Then you could use
the include_stylesheet helper to add the autogenerated css file.
That way you can isolate all of this within a single component which
will keep your code cleaner. You could test to see if the css file
had already been created and use it, otherwise create a new stylesheet
with the directives in it, write it then include it. Then if things
change down the road, you just update the component, say if you needed
to also manage height or something.
