Quick Q

I managed to recode my den's layout, but was curious if someone could help me with a quick question I had. 

To do a forum post, do I still need to dropbox my code I wrote out in notepad, and use the link="x"... blah blah and then my link or do I need to code using HTML > CSS for forum posts?

Because my code isn't working when I paste it. I've checked the individual pieces of it, and each individual component works, just the forum isn't actually encoding it--it's just posting the actual textual writing of the code. 

For instance this is what is coming up from the first part

body { background-image: url("https://wallpaperaccess.com/full/1373773.jpg"); background-repeat: repeat-y; background-position: center; background-color: black background-size: cover; background-attachment: scroll; }

Sorry if this has any errors, I'm in the middle of my break at work and have been simultaneously dealing with registering for Classes (stalking the campus registrar lol so I can get the right section). 

Hope you got in the classes you needed/wanted! As far as I know the forum will wipe CSS in the style tag and linked files. But inline CSS, and using that on HTML table layouts, should work just fine :>

ahhh alrighty thank you! :D
