I tried the "Responsive Image Grid" code found at: https://www.w3schools.com/howto/howto_css_image_grid_responsive.asp
It's all working as designed BUT
1) Images do not resize if you narrow the browser and
2) I'm missing a feature I'd like to add and have no idea how to do so.
>> Is there a way to allow a user to click on a thumbnail and get a full-side version of the image?
Here's the example "Try It" page for the "Responsive Image Grid" https://www.w3schools.com/howto/tryit.asp?filename=tryhow_css_image_grid_responsive
You can see my draft implementation (yes I know it's sloppy) on my staging area at: https://techlab2020.com/hypno/gallery.htm
Thanks, all
