Hiya Sakura!

To style your den page through CSS, you will need to write the code you want in a program like Notepad or Notepad++. Both of these are completely free but I highly recommend using Notepad++. Notepad however is usually automatically on any windows computer, you'll just have to search for the program.

Also, if you're using Notepad to code, when you click the "Save As..." button add .css to the end of the name and make sure to change the "Save as file type" to "All Files". Otherwise it will be saved as a .txt file which will not work.

Example:

Once you're done coding it, upload it to Dropbox and link it to your den. Here's a guide to teach you how to do that.

I hope this helps!
Additionally, if you ever need anymore help or have anymore questions feel free to PM me at any time. :)
