W2: Class, Readings and more.

I read the Wikipedia entries for HTML and CSS on the weekend, some comments follow.

HyperText Markup Language (HTML): I learned what HTML 4.0 and XHTML were, didn't know this. Learned about the structure of HTML and its markup element types: structural, presentation, and hypertext. After seeing this structure I saw how content (in HTML) can be separated from the style (in CSS) and that HTML 4.x and XHTML are strict about this. I also read the Wikipedia entry on Separation of style and content learning about the benefits of this approach.

Cascading Style Sheets (CSS). I saw concretely how one can modify the style HTML tags on the CSS. This was interesting because I had never understand it before, but know I see how simple it is. I also learned how CSS can be inside the HTML or in a separate CSS file. The examples and its explanations help me see it in action. CSS can get complex if you want to, and there is a lot of freedom on it. It suprised me to read that no browser has completly implemented CSS, so the newer versions of CSS had to remove features. I played around with the simple examples; I saw CSS working.

I also installed the Firefox Web Developer Extension. No problems with it, its working. I played with the options, disabling and enabling the CSS and Images, Outlining the webpage design. I can see why we need this extension.
