Implementing a modal(lightbox) for all images in all post-gallery posts

The question:

I’m trying to make a photo gallery page for all my photos in my post-gallery post and have a modal open when you click on the photos. In the page there will probably be almost 100 photos and i’m not sure how to do this in a good way without duplicating the code for the modal 100x. I have considered using plugins but i’d doing this as part of making my own website and learning developing wordpress themes so i’d prefer if the solution is done with code.

Something Best practice solution for this situation would be great!

I would appreciate tips in how to do this!

The Solutions:

Below are the methods you can try. The first solution is probably the best. Try others if the first one doesn’t work. Senior developers aren’t just copying/pasting – they read the methods carefully & apply them wisely to each case.

Method 1

This W3Schools page shows how to create a lightbox with HTML, CSS and vanilla JS only:

If you have lots of photos on a page, you may want to remove the code related to the “thumbnail image controls” that they use in this example. But, other than that, I think their example shows what you want to do.

Another solution might be to use a jQuery-based library like Fancybox:

Method 2

i’ve found a solution for this using jquery. i set up an event that when you click on an image it opens a modal and gets the url of the image from the gallery and places it to the img tag in the modal. it works alright but it feels like a workaround atm
