Coding is fine; you seem to have a good knowledge of it. Perhaps you could help take a look at why our background is broken? I certainly have no clue, was going to do some reading into it though. If it is a simple fix though your help would be appreciated!
Great! ^^ Cuz I really wanted to spice that page up :P XD And yes, I'm the coder on all my Wikis, so I know a considerable amount :d Actually, I did ask Heimr Arnadalr about that! Sure, I can take a look, just give me a few minutes please! ^^
Okay, I see the problem. The image for the background was uploaded on a different Wiki, and that Wiki has been deleted, so the image has also been deleted subsequently. The Wiki was dragonboys-playground.wikia.com but if you click the link you'll see it doesn't exist anymore, you'll just get redirected to Community Central's error page. (The image for the background can be found here, I believe, and you can see at the top of the page that it is still displaying the broken file.) Do you guys have a backup somewhere? If not then I can look into the wayback machine and see if anyone saved a screenshot.
Also, this Wiki doesn't seem to have any images with transparent backgrounds other than the wordmark and snowflake image, I was looking for ones similar to the deleted ones. Was that done on purpose? I didn't see anywhere in the MOS about transparent images :d
Sorry XD I know that I tend to get spammy when I reply too much >n<
Oh, lol XD
Yep, I sure can, but the Wayback Machine is being finicky with that page for me -.- Is it okay if I use this version? I would have to use Inspect Element to get at the full image, then I can screencap it and upload it here. After that's complete, you would need to either replace the code in MediaWiki:Wikia.css, upload it in Theme Designer or upload it in File:Wiki-background.
Ah, okay! Well if you want to upload a backup here just in case it ever disappears then that could be a good idea :d
I think the highest it's ever accepted for me is 1600 x 1200, which is 190.7 KB and it covers the entire background (well, at least it does on my normal laptop, I'm not using my normal one right now but it still covers the majority), maybe resize it? On the Disney Princess Wiki (I was talking about affiliating with this Wiki with Heimr) the background seems to be fully or almost fully covered and it's 1500 x 990 or 118.5 KB, so I know for sure those two sizes work.
Well, the best I could manage is what you see at the moment. I've had to split the image; even with a width of more than 2000px the image still won't allow me to not have it split, as it disappears and leaves the broken/missing file image.
You can also see the split at the very top and bottom of a page, and it would be nice to get rid of that too.
Okay, I see, it still looks good imo, tho :P Okay, so, I can see that the width is 2200 and the height is 1037 from here, but it looks like the image already has the blue split from itself as opposed to TD. I would try just uploading the normal image and playing around with it, here are some I found:  Sometimes you have to really mess with it to get the right result, like this is what I had to do to get the proper look at w:c:elfquest, and that's just set to no split in TD with nothing else. (That Wiki isn't done yet tho btw, the Head Crat is away but they plan to fade the background image to white until it blends with a completely white background, which is currently the blue part rn.)
