Configure your user.css boilerplate
Hint: You don't have to add both layout types if you plan to only use one. In fact, it will unnecessarily blow up your user.css. Please make sure to enter sensible values in the form fields. The generator does not check the values you enter.
Also note that a stylesheet generated automagically like this one will most likely look a bit dull compared to a handcrafted one. Especially the color scheme will most likely merely be a starting point due to the limitations of the (or any, for that matter) generator.
Your user.css boilerplate code
Copy and paste this section into your user.css. Remember you need to create that file and upload it to the template directory as well as explicitly activate it in the theme options.
