Multiple Aspect Ratios

I want to have one page of portfolio images (2023) to all have an aspect ratio of 1:1, and have another portfolio page (2022) to be 16:9. Is there any code that can do this? Thank you!

Please see the following.

Let us know how it goes.

I have to upgrade my plan for the code injection step when installing twcsl. Is there no way to do this without paying more?

There may be a CSS only way but I know of no code that does this.

A CSS only solution would be more fragile and may take a fair amount of work. You'd basically be overriding a number of classes for a particular effect.

The advantage of my code is that instead of overriding a bunch of CSS it is replacing the one class name on the body tag to make the aspect ratio change. You can kind of think of it as a programmatic switch that changes the AR.
