Responsive Art Gallery Website

I would greatly appreciate your feedback!

• I used Leaflet to make a map for the location screen. Changing a marker turned out to be quite a challenge since it was my first time trying that. I didn't realize I needed to use a special function for it.
• I'm not too sure about the big title (h1) on the home page and how I made it have two colors. I tried using mix-blend-mode: difference for a two-color effect, but it's supposed to be just black and white based on the design. Unfortunately, because of the image, I couldn't get it to be completely black and white.
