I am confused on how it works, my boss wants to implement it, mine works but I feel its not optimized.
I tried:

SDC - Single Directory Component;
Custom Module with Custom Blocks;

Right now I switched it up a bit, going with bootstrap only but I feel I am losing on that modern feel.

Do you have Recommendations?

I am trying to make a gallery, I want to learn more about drupal but I dont know good sources on how to find such things.

I would like to know if there are any modules
I tried:

• Colorbox
• PhotoSwipe

This link is what I am trying to achieve.

I tried with views too, I am in road block.
