For some reason my document will not render the styles.css file that I created. When I open the after document it renders it fine, but it doesn't work in my work folder. No colors, and the font is appearing as whatever I set it to in Internet options. I went into the options and changed the default fonts and that changes my work document. I copied your stylesheet word for word, but it will not take effect in my html document. Very frustrating. I will figure out why though, dont worry.
edit: Got it, I was saving the file with the name work.html in the before folder, and not the work folder, now I just renamed it to lesson3.html in the work folder and it is working.
I just wanted to post this in case someone else made this dumb mistake!
