Events in CSS

          The latest version of CSS as of now is CSS3. The main feature of this new version is that it makes web pages (1) more interactive with users by supporting animations and (2) more responsive and adaptive by being able to adjust to the device where the webpage is being viewed.

          Because of CSS, there are also many tags in HTML that are no longer used. Some of them include text-formatting tags like <bold>, <i> , and <ul>.  Some tags used for layout are also rendered obsolete, such as <center>.
