Because idea is to have paper background for some content like we have for Encounters and some other events.

I'm gonna create Animated CSS like when You select item and little table to look like items in game, these things can thankfuly be made just with CSS. Paper background will be used for stuff like for example Goblins Cards You can see in Enemy page I created ( and used like 200 hours of my life in it already xD )

On top of that these paper pages can be easily animated so for example if You hover Your mouse over it paper can tilt or move like normal "paper page"

That's why I translated message using ChatGPT so he don't have to struggle and waste stamina on attempts :P

Also... Im not sure what You mean by red background border like one in equip menu...

I can't remember about any red background in Lona... :/

I did used that texture at first but It was looking very bad when stretching it as background, so i decided to make it as repeating border and then fill with either random semaless tiles background or just with solid color.

only thing i need is to have texture that have only 30 pixels of "dirt" on edges and goes into solid color in center.

if center of the picture is too detailed then You can see many edges at page borders with center :/

Ohh I have an idea,

If You could edit that texture on edges so there is no so much visible  "border" between then.

Browser to create container on Wikia will sample texture on edges and create any resolution page as needed so we can have containers of 300x200 pixels or 500x500 pixels etc. I know I could use picture as background BUT... it's only good when You work with high resolution pixtures because streatching not gonna be visible, in case where we have PixelArt we don't want to stretch pixels around so seamless to center texture is required :(...

I got a friend to make little edits to that texture for me, but his works is kinda far from perfect.

I hope It could give You general idea and here is how it currently looks like:

Here is version created by him, problem with that texture is that as You can see it's not seamless, in order for it to be "connections" between corners and borders should be seamless... well it do look much better now but if You could make that little one fix I would be really happy ^_^

Here is texture that Wikia currently uses:

I have no idea what is Kirita, I'm not Artist I'm programmer xD 

Just Googled it, it's some soft for drawing i see... well never used it :x... I use Paint and Gimp sometimes xD
