I really like the whole idea of external style sheets. It is really useful if you are making a website with mupltiple pages because you can link all the pages to the same style sheet so it all looks the same and is much easier then putting internal style sheets in each one. This is good to save time and it helps with web usability . Some stuff were talking about in class is web accessibility, it's amazing how theres so many things that go into websites to make them accessible to everyone. They have to be readable by all persons, for example, people that suffer from blindness . So all websites have code built in that can be played by certain programs so blind people can access them to. What it does is read off everything on the webpage in a certain way to web site designer creates to make it easy to understand. Everything on the web should be accessible by everyone just like everything in real life is accessible to everyone.
