The teacher started showing us the 3 different methods to use CSS in an HTML: create a style file, create a style inside the HTML file, and add style to a specific tag inside the HTML.
We continued using the most used method and the best one (In a sense of clearness and reuse, since the 3 methods do the same), we created a style file, were he showed us how to style html tags by directly referring to them, a specific HTML item by using the id, and create classes that you can apply later in the HTML code.
After that he talked a bit about the fonts, text and background properties. Then he talked about the important span HTML tag, used to style small selections of a page, but the most important one is the div tag, the most used tag to format a page (it can be considered the substitute of the tables), and ended with the positioning properties.
The class was pretty interesting, but it lasts only 3 hours, so the ones who know about coding will realize how basic everything was, so...now its time to grab a book and learn more about this.
