I learnt about CSS, which is mainly about how to customise your website. CSS is very complicated, like HTML, and requires 100% precision: any slightest mistake will completely screw up the document. CSS is very good though: as long as it is put in one folder and all the HTML files in the folder are put together with CSS applied, it will change the style sheet for ALL the HTML files. Assuming you have stylesheet A, HTML file B and HTML file C. One day, you decide that you want another type of stylesheet A instead. So you edit the values of Stylesheet A, save it, and voila! All the HTML files have been updated. However, this sometimes causes problems. The html only requires <>, but the CSS uses {} instead. Also, inserting the correct values for CSS can be extremely tedious as well. However, once it has been perfectly programmed to your desire, everything would go easier. CSS is an extremely good tool to use. And thus, if you do manage to insert and memorise every value correctly, you don't have to waste space on your computer or trying to remember what pictures for what background.
CSS links are usually placed after the title tags, but before the closing head tag.

Lesson 3-HyperText Markup Language
Note that all the tags had opening and closing removed. Sometimes, being smart is bad.
I learnt about HTML today. HTML is a simple but tedious coding of websites that usually requires a lot of patience to memorise the codes. HTML is the basic foundation of all websites: it is the most common markup language, and all browsers have been programmed to recognise html. This is usually in the form of the html tag. HTML has several tags which are the BACKBONE of HTML itself. They are the head tag, the title tag, and body tag.
The head tag basically does nothing in basic HTML. It only contains the title tag, which is put on the blue bar on Internet Explorer, and Mozilla Firefox. The blue bar is the bar that appears on the top of a program. For example, if you are on Wikipedia, the blue bar would show something like "Wikipedia-The free encyclopedia-Mozilla Firefox". This happens even if you are not using a browser: My Documents would show up if the file opened currently is My Documents.
The body tag is where most of the work takes place. It is where all the words are written. Usually, every other tag will come here. The tags are usually e or i for italics, u for underline, and h1 for biggest words. The body tag is usually a MUST in HTML, or else, a blank screen will simply appear.
HTML is extremely precise: If you missed out a letter/misspelled a word, the entire page will be horribly screwed up, with blank screens occuring most of the time. Also, closing tags are required for some tags. They include the basic tags, which are html, body and so on. To do that, one adds a slash before the words, like this:/h4

Lesson 2-Social Media, IP, Copyright, Blogs Forum
I was to post on the Blogs and websites Forum, since my register number came in the last 9 of the class. Blogs, in my opinion, may be biased a little, since they are written in the 1st POV, thus, creating potential biasness. They are however public, which means that the consequence portion of freedom of speech has to be exercised, or else, you might end up offending someone, a religious group, an important person, your teacher, peers, etc. You may even be sent to jail!
The 2nd topic I looked at was Intellectual property and Copyright. Beneath the surface and facade of an extremely funny and hilarious video lies the fact that you cannot copy entire pages for official purposes. In fact, you can only copy stuff for your own personal viewing, but if it is presented to an authority(or even your peers), you are simply infringing copyright. You can only copy up to 10% or 1 chapter of a reference book for your own usage. In order to copy even, the author must have given permission. Even in Wikipedia, sources are given for information found in entries, so there would be no point copying from it and not giving the source as either the original source, or Wikipedia. It is simply wrong. This is because the author is entitled to royalties from selling books, thus, if photocopying of reference materials is abused, the money only goes to the photocopying company, and the author gets absolutely nothing. This will put off creativity, because of the lack of benefit, or to put it more specifically, MONETARY benefit. Soon, this chain reaction would completely collapse the writing industry. Thus, copyright laws had to be imposed.
The last video I watched was on Social Media, namely, its impact on man. It is basically futuristic, seeing that with the flick of a finger, or the push of a button, you can get your organiser to remind you of what to do. I feel that this would however, be negative, since you basically rely on mechanical objects to remind you of everything, to completely cut your work by at least half... it just does not sound right. We are after all, not machines, so there is no point in advanced human-computer interaction. It is only meant for the Homo Sapiens who would in the future, evolve into beings that rely on brains and psychics instead of muscles and communication.

Lesson 1-Web 2.0
I learnt that Web 2.0 consists of people hosting a website from multiple servers, or people contributing to a website from different places. Web 1.0, the older version, has only an adminstrator, namely, the person who created the website, updating info. Examples of web 2.0 usually include wikis, message boards, and forums. Only 1 person(the creator) can edit a website in Web 1.0. This means that other people cannot see contributions made by other people.
