My website was written in Phoenix Code's editor, free edition.

I learned HTML and CSS starting with W3Schools.
I also watched various videos on Youtube, such as the ones on Coding2GO's channel.
There also was and always will be a ton of simply googling a specific problem I was having and kept ending up on stackoverflow.com, where people had already asked similar enough questions.

Much of my images are hosted on File Garden

Graphics

The site's main background (diagonal stripes) is my own creation. All other backgrounds like these

were sourced from background collections such as yay-backgrounds and snaappy's masterpost. My Pokemon page's background is from one of these, but with colors changed. This is the original.

Paper and fabric textures from Texture Town, with colors also edited
Other cute textures/backgrounds came from Hillhouse's materials page.

Stickers pasted around the background are from various sources such as Fairytrash's Sticker Page, Pinterest, and scans of my own stickers. I think many of them, but not all, are old Sandylion stickers.

Pokemon graphics are from the official games, and I got the files from Serebii and Pokemon Asset Archive

Yoshi graphics are also from official games, with the files coming from Mario Wiki (Yoshi's story) and GifCities. Not sure where I got the yarn yoshi gif.

Really awesome and cute pixels from King-Lulu-Deer's pixel gallery

"Made with pride" button from msx.gay

Glitter text made on Gigaglitters.com

Various other graphics from GifCities.org

Inspiration for the tape decorations comes from Hill House. I didn't use the same code because I didn't understand it well enough to play around with it as I wanted, so I wrote my own less elegant code.
