Website Name:CSS Zen Garden
Website Purpose: Examples of CSS
https://www.csszengarden.com I liked the simplicity of the website. You could click links to the different designs Also as the website explains they use functional and practical CSS, not the newest tricks only viewable by 2% of the viewing public. Beyond that the Examples given are pretty neat.
Yes, there are a few warnings for unnecessary elements.
I went to the apothecary CSS page, this page validates with a few warnings.
The home page had 4 warnings. Second page Apothecary had 4 warnings.
I give this site a 9. This site has some cool CSS pages displayed in multiple different designs. Although some of them are not to my preference it still shows what variety you can achieve using CSS. Some have animations as well.
I'll give it a 10 Simple layout, the content is the same throughout. It only changes the design using each link, so it is easy to understand. It also provides example files of the html and CSS which is pretty cool for reference.
Yes, it shows examples of CSS and even gives examples of the code used.
