so what is ccs ?

css are the sigles for Cascading Style Sheets.
instead of controlling them by an especial program like when we used HTML we used bluegriffon for this one we easily just open it in the notes blog from the computer.

AND HOW CCS STARTED... ?
originaly you could only use HTML to do web pages because it was easy and a lot of people started using it more and more looking for a better estructure of the texts and parografs so the invented more and more HTML codes, but people where using it them wrong so the invented the ccs to offer a larger range of format oportinities and at the same time thanks to the format of this program it was easier to understad it, so a days every web page style is based on ccs and not HTML
