Thank you so much for your detailed instructions.
I have only just had a chance to implement them on a test page: https://trojanmun.org/2312-2/
I do have a few followup questions that I was hoping you could answer. Firstly, as you can see when you click the first image link, the images in the lightbox are not vertically aligned. For some reason, I cannot seem to fix this problem and I was wondering if you had any advice about doing so.
I’ve also been having trouble editing the text styles within the lightbox. I can’t seem to find the right CSS file to edit to change these styles.
Again, thank you so much for your help on this. I really appreciate it.
