Mi fox got CSS'ed

Ive "worked" on the template last week, manipulating some basic code and using some logic, i've managed to understand a little more of CSS (Cascade Style Sheet) and ended up with a nice subtle change in my blog. Worked perfectly. All the main with a gray background, and all endorsed to a lighter gray background. I was pleased. Left work with no interesting thought but figuring out what could i do with this spotless page of my own.
As im doing right now, i do many non-work-related things at "work". The lack of job lately and a "nice adjusted" computer with a "not-so-protected-web-content" allows me to navigate with the market-whore Internet Explorer while i hang my feet on top of a little drawer (which, among other useless things, i keep my Knorr Quick Instant Corn Soup.).
This being said, and missing university for a discontent feeling of pleasure, that same day i took the bus to home, planning in its travel to post about each thought it may occur to me (and the way it varies) during the travel time. Reaching home i went straight to my 4 months old 'not-so-lap'top. Of course i use Firefox at home. Who wouldnt ! Its fast, it has tabs, it makes you different for not using M$ IE, and it looks nice !. Again, who wouldnt !. I do have to admit that i got pretty (i wish the sentence would stop here) excited (Better stop it here !) with the changes ive made, not because i felt it was a hell of a job, but because i know nothing about CSS and never read anything about it. "So i was there, and i sat on my comp chair, and flipped the screen... and.. and.. oh my god, oh my god, you wont believe it !.. and.. and.. well.. i dont remember...". Oh yes, I do remember. Nothing special tho. I just started to navigate through some bookmarked pages and links and suddenly realized that this, my blog, wasnt looking exactly as the time i left work. Confused, I browsed through my pc until i found the ie icon and opened, again, my blog (such a self centered boy...) and compared the two browsers. Of course ! my firefox isnt showing the dark gray square that should be filling all the text ! It is only a small rectangle below the title and above the main !
-Como puede ser !- I said (well, i admit it would be freaky if i said at home "how could this possibly be !") and google'ed, in my firefox of course, what would be the reason of such injury to my crappy design !. Suddenly, i remember why i left my old blog in the attic. It is known that CSS does cause some problems with FireFox due to the fact that CSS was developed... wait.. nevermind.. i was to upset to find out the why. Ends up that my poor knowledge of html and CSS plus the notorious neccesity of doing nothing can do nothing to save my Fox getting CSS'ed.

Posting these lines, at my work, with one foot on top of the drawer and my polo shirt button scaping from its flap.
