HTML – Beginner’s guide to Use Tags
Now that you have already created your web page, we should examine some segments of “index.html” file. Certainly you have seen that there is a model in the arrangement of the commands , some words are surrounded of “<” and “>”, these are HTML tags.
An example of HTML tag is <body>. The <body> tag tells the browser, where the content of the web page begins.<body> is an example of tag who must exist in every web page.
Base tags in HTML
Lets take a look at the code. A web page has in composition two base elements. If you try to create a page without those two tags, you will have problems.
<html> <body> Web's page content will go here </body> </html>
First tag is called <html> and is the tag that tells the browser that it had started a HTML code. The second tag, <body>, tells the browser that from there it had started the visible part or page content.
How to close a HTML tag
You may have observed already other two similar tags at the end of the document, </body> and </html>. These tag are for closing.</body>, lets the browser know that page’s content is over, and </html> that the HTML document is done.
Slash “/” is situated before tag’s name and it tells to the browser that he wants yo stop the current function. So <tag> is used to start a function, and </tag> to stop it.
Tag’s order – very important
The order of opening and closing a tag is very important. If a tag is opened in an other, for example body is opened inside html then that tag (body) is the one who needs to be closed before the parent tag (html).
We have closed first body because it was the last one opened. This simple rule (opening and closing tag order) applies to all other HTML tags.
The second page
You may need time and more attempts so that you get used with this rules, so you should keep trying with the next web page. Copy this code in notepad, like you did with the first page.
<html> <head> <title>My second web page ! </title> </head> <body> <h2>Welcome.</h2> <p>Very soon I will make a page which is going to be so cool!</p> </body> </html>
After you have assured that everything is going along with the anterior indications, you can save the document. You could try to save it with the same name as the one before, “index.html”. You may be asked if you want to overwrite the document, select OK, we won’t need any more the other document. When you are done, go on and read the next tutorial.

Two Machine Learning Fields
There are two sides to machine learning:
- Practical Machine Learning:This is about querying databases, cleaning data, writing scripts to transform data and gluing algorithm and libraries together and writing custom code to squeeze reliable answers from data to satisfy difficult and ill defined questions. It’s the mess of reality.
- Theoretical Machine Learning: This is about math and abstraction and idealized scenarios and limits and beauty and informing what is possible. It is a whole lot neater and cleaner and removed from the mess of reality.
