Nightfall | menu bar utility for toggling dark mode | Menu library

I am working on a project with a docker-compose.yml file having lots of interdependencies:

my first ever StackOverflow question, having been banging my head for about 4 hours!

I am building a react page that has an image gallery section. On the desktop site, when the user clicks on an image, it launches a Bootstrap modal pop up that should show the details of the clicked painting (title, size, type and media) and a larger image.

I have got the modal working (without needing any special library like react-bootstrap) but whichever image is clicked, the modal only shows the image and details of the first image in the set.

I have tried all sorts of permutations of props and state, trying functional and class components, and nothing seems to work.

Weirdly, if I look at each component in the chrome dev tools react DOM, the props for each image are set correctly, even in the class that renders the modal...but in the actual rendered page, it does not work.

In my code, we have a Gallery component, containing many Holder components, each Holder contains a PortfolioItem, and the PortfolioItem contains a component called More that deals with the modal. As each Holder component defines props, these are passed down to each PortfolioItem (which works as I am getting the correct images and details in the gallery) and I just want those same props to show up in the modal.

I have a file called config.js that I'm using as a config file:

I have an RDD with lines of text in it. The text is from a text file and it has new linefeeds (returns). I am looking to place quotes on the first word and the last word in the RDD.

I'm creating a slideshow of specific projects for one of my clients. When the button is clicked it's supposed to append the slideshow with all the correct images to the div with id"slideshow". For some reason when I click the button nothing happens. Can someone look at my code and see what could possibly be wrong?

I used flex for defining the inline content however when I use the media query property I see that once I pass to the smartphone view the header/menu bar gets behind the section (#media).

How do I solve the problem? I tried changing the display property but still the problem persist and other properties but nothing work the second contend hide the menu bar.

HTML code

In full disclosure I know very little when it comes to java but I did find a script online that accomplished exactly what I was looking for so I borrowed the basics of it and miraculously I was able to successfully implement it into my project.

However after endless trial and error attempts and then googling for over an hour I simply am at a loss for how I speed up the 'transition' for this function. Basically when I click the button 'open-overlay' it opens a full screen mask with a message in container 'overlay' and then when I click a second button it closes. All great and good but it takes probably 1000 to open and the same to close. What would I add to this script (and where!!!) to adjust that to 2/10ths of a second or maybe even 0?? I have reproduced CA's codepen here. Thanks so much in advance for your help and apologies for asking a question that is probably java 101! Jorie
