Tell me your idea/thoughts about the mobile responsive version pages, although I'm still struggling with index page, also gonna redo these buttons from link page since it doesn't work too much on different size screens...

Funny how no matter I found more artist's gallery webpages, I still have no idea how to design the gallery

Not sure what kind of gallery you want to make, but I used lightbox - https://lokeshdhakar.com/projects/lightbox2/, and collapsibles - https://www.w3schools.com/howto/howto_js_collapsible.asp

If you're talking about gallery, I would like to make little thumbnails which click to open the full sized images, but I'm struggling with UI/design ideas, the collaspibles looks useful, I'll try it out if able!

Also thank you so much for idea!

There's probably a quicker way to do it these days, but I make the thumbnails myself. I create a new canvas (100 X 100 or whatever thumbnail size you want) and copy your image (or a piece of it) on to your thumbnail. For displaying the gallery, aside from the collapsible and lightbox, I use a very simple set up, so feel free to view the source code on my art page.

May I reference your layout? Although I have same idea as your layout before check your webpage, which is coincidence

Yeah, go for it!

Thank ya!
