HTML IS NECESSARY FOR HACKERS
Hello guys today I am going to talk about basic HTML which is useful for hackers in many purposes. A hacker must have basic knowledge about HTML which makes easy to understand web pages,XSS , phishing etc. When there is a vulnerability in victim’s website, a hacker must have a little idea about what it is. Hence he must get used to HTML to identify and take control over the website! When I entered in the world of computers,blogging and hacking I was not at all aware of HTML but having a regular touch with web
pages and there codes I was able to learn and understand it. HTML is very easy, you just have to be a quick learner to get to know it! So below are few lessons which help you to get a basic notion…
Lesson 1: Introduction to HTML
HTML consists of lot of tags which are used to design a webpage.HTML tags are keywords surrounded by angle brackets like <html>. HTML tags normally come in pairs like <b> and </b>. These tags are like a set of commands. The first tag in a pair is the start tag, the second tag is the end tag. Start and end tags are also called opening tags and closing tags. Every code starts with a simple tag “<html>” and end with “</html>”. The text between <html> and </html> describes the web page
Example:
<html>
<body><h1>My First Heading</h1><p>My first paragraph.</p></body>
</html>
<body><h1>My First Heading</h1><p>My first paragraph.</p></body>
</html>
The text between <body> and </body> is the visible page content. The text between <h1> and </h1> is displayed as a heading. The text between <p> and </p> is displayed as a paragraph.
Lesson 2: Create your own test web page
If you want to create a web page on your own computer, just right click the link, and select “save target as” or “save link as”. Save it with any name wich ends with “.htm” or “.html“
After you have saved the files, you can open the file which you have saved and see your first web site in action.
Similarly you can create more pages by just writing few simple codes in notepad and saving it as “.htm“
TIP: I suggest you experiment with everything you learn here by editing your web files Notepad.
Lesson 3: HTML basic tags
HTML headings:
<h1>This is a heading</h1>
<h2>This is a heading</h2>
<h3>This is a heading</h3>
<h2>This is a heading</h2>
<h3>This is a heading</h3>
HTML links:
<a href=”http://www.vjblog.co.cc”>This is a link</a>
HTML images:
<img src=”http://www.google.co.in/intl/en_ALL/images/logos/images_logo_lg.gif ” width=”104″ height=”142″ />
Empty HTML elements:
HTML elements with no content are called empty elements.
<br> is an empty element without a closing tag, the <br> tag defines a line break.
Lesson 4: HTML reference attributes
Attributes are the worlds used inside a HTML opening tag to adjust the title, class, width and height (if image).
Example: <img src=”http://www.google.co.in” width=”104″ height=”142″ />
