[Help] I don't know what I'm doing.

I've taken the God Machine character sheet code off of GitHub and have been making changes to it. For some reason, no matter how small, anything I do is causing the whole thing to go completely blank. It's really disheartening. It was working fine, I changed the logo and it functioned perfectly. HTML I added one text line on each column and that's literally it. I actually don't know what broke it, because I went back and removed the lines that I pretty much just copied and pasted and it's still blank. The original code edit: I even tried re-pasting the original code in there. Nothing. Why would it work one time, and then not the other?

This is what I get when I put your html in (and the css from Github): What is wrong with it?

To add on to CPP's response...if you are looking at the Preview tab and that's blank, that's pretty standard. The preview tab is notoriously wonky, so when it's blank, your best bet is to just save it and and then launch the campaign to see what things look like.

And use the Dev server preveiw pane.  It is a bit more stable (but not a 100%).  As I have no idea how such a system works, how to improve it, or anything else, I am not complaining. 

Seems to load up in game now that you mention it. Thanks for that tip! I started messing with the file a little more and it isn't going blank anymore either. However, this happened when I tried to move the equipment table: The spacing is really weird and I don't understand why. Maybe this is something covered in the CSS, I dunno. link

No, its cover in the html code: Where is says style="width:##px;", change the number in the weapon name inputs to match what is on the equipment name inputs (200px, I think).  Each Dice and Damage should be set to the same width as Durability and Structure (um...100px? Maybe?), and size and cost should match Range and Clip (which are 75px and 55px, respectively...I think).

Awesome, fixed it! Thank you!

Glad I could help.
