- 1994 – Cascading HTML style sheets
- 1996 CSS1
- 1998 CSS2
- 2012 CSS3 Where is it??
HTML has a simple structure, universal semantics, media-independent. It doesn’t have any presentation until the image tag arrived. Somehow the image tag took away the true text. The answer to this was CSS.
Example: The menu on Apple.com is currently done with images – it could be done fully in CSS3. The problem is (and probably the reason Apple has not done it with CSS3) older browsers do not support this.
- @font-face (this has existed since CSS2)
- transition: 1s; transform: rotate(-360deg);
- The acid 2 test was created to test browser compatibility with CSS. This put pressure on Microsoft to handle CSS correctly. In IE8, they finally did it.
Paging the Web
- Opera Reader takes a long web page and gets rid of the scroll. It cuts it up into pages.
- overflow: paged; is the tag that the Opera Reader recognizes.
