CSS

CSS stands for cascading style sheet which changes all of the formats of the documents in the same folder. I was originally not sure of how it worked until I saw it in action. The documents that you want to edit and change formats and designs should be in the same folder. If they are not in the same folder, they will be unaffected. If you move a document from a folder that already has a CSS to one that does not, the document will probably return back to normal. Like the html files which are directly linked to the internet, the type of the file is determined by the word you put behind the file name. For html it is '.htm' or '.html'. For CSS, it is '_css.html' or '_css.htm'. Like the html files, I still wonder how the computer can sense the words you put behind the name of the file (.html). But the CSS format is very complicated and I don't think a beginner could easily do it, unlike the html, which can be simply done after some lessons. The whole format is very confusing and probably only professionals can create whole new CSSs'. But still, they are necessary for sprucing up your whole webpage.
