Ayy so guess what I did. My website now has a style switcher, in the day time it will use daytime.css, the bright and colorful one. In the night time it will use my tried and true style.css, the same style it has used for the past year. Or, in the footer of every page, you can manually switch to either one. The switcher uses a PHP session.
Don't look at my portfolio. Seriously, it's dog shit. A big wart on my website if you ask me. I'll finish it one day. Should be in the next 5-10 years.
