What happens with tags that don't have a closing tag?
Tags that do not have a closing tag will probably not render. If it's somthing like the <html> tag or the <body> tag, the whole web page may not work.
How do you make a pop-up window from HTML code?
You cannot create a popup using HTML. You need to use a bit of programming code, like a scripting language and build that into the web page. The alert command in Javascript or the prompt command for example, can do it. There are lots of ways in different languages.
In web context, absolute links are those that have a full URI in the href attribute, for example: absolute link to this answer Relative links specifies the address relatively to the current page. Since all other pages on this site share the same "root", you can specify their href attribute without the http://wiki.answers.com/Q/ part: relative link to this answer
What is the different between XML and HTML?
HTML is a language used to build web pages. XML is a set of standards used to create other languages.
HTML is a markup language defined by the World Wide Web Consortium (W3C) and primarily used to code web-pages. HTML gives a group of pre-defined tags, like <BODY> and <A> and <LINK> that have well-defined uses and generally accepted default styles in modern browsers.
XML isn't a language at all. Rather, it's a particular syntax for setting up a language. It creates that idea of an element, and give those elements content and attributes. XML allows a programmer to create a language that is defined to specifically suit her needs. This is done one of several ways, but the most popular are by creating a Document Type Definition or an XML Schema. These documents define the behavior of the language itself.
HTML and XML are combined in the ubiquitous XHTML 1.0 and 1.1 specifications from the W3C. XHTML is being supplanted by HTML 5. HTML 5, by default, isn't an XML based language, but you can use XML-style code by changing the MIME type to application/html+xml.
A second version of XHTML was in the works at the W3C, but work stopped in December of 2010.
xml uses tags to describe data, any computer can then read the data using the tags.
A "Hello world" program is usually the very first program you write when learning a new programming language, it simply prints out the text "Hello World". Below are a few examples:
PHP:
echo "Hello World";
_____________________________________
JavaScript:
document.write("Hello World");
_____________________________________ Visual Basic:
Module Hello
Sub Main()
MsgBox("Hello, World!") ' Display message on computer screen.
End Sub
End Module
What is HTML template framework?

What attribute is used to specify the thickness of a hr tag?

{
// (do something here)
}
Where is the best place to buy a website?
There never really is a "Best" place to buy webspace; Every web host company offers different things. Different people want different things. Perhaps you need the PHP engine to be installed, or have it pre-installed; To have MySQL operatable on your website; So on. And price is always a factor, too. ---- One example of a good host is BlueHost. At the time of writing, they offer unlimited Bandwidth and Web space, Ruby on Rails, PHP, several database engines, and a whole lot more. They even provide you with a free domain.

Both. It runs on the browser but can request from a Server.
Similarly to Ajax the side is unclear. Client side is the best fit with requests.
How do you create a login page with user name and password fields?
It is quite simple to create a login page, it is simply a form input, if all the people hold the same username and password. If you want and I suspect you do, a unique service, then you will need to install a database. I have no experience of this.
Some programs require XML-structured data. But there are ways around that, so if you know that programs do not need XML-structured data, then no -- you do not need XML.
XML 4.0 is a version of XML that does not yet exist.
The latest version is 1.1, visit the w3c site to see the spec
Which is better to use while submitting a form GET method or POST method?
If your form has security items (like username, password) use POST method. Because post method is more secure. Otherwise you can use GET method. Also GET method is faster than POST method.
What is a frameset tag and its attributes?
The frameset tag is used to define the layout of a web page which uses frames. It defines how many frames, their sizes, and what pages get loaded in each one. A web page which uses frames actually calls for separate web pages to load in each frame. The attributes and further description are all listed here: http://devedge-temp.mozilla.org/library/manuals/1998/htmlguide/tags11.html#1294825

What is the difference between WebService and API?
web service is like advanced Urls and API is Programmed Interface. API contains classes and Interfaces just like a program. A web service is a form of API (Application Programming Interface). An API is used by a computer programmer to establish a link between software applications. This interface can take several forms, a web service is just one of these. There are several types of web service. SOAP (Simple Object Access Protocol) is one of the most common. The API takes the form of a service description (WSDL) which is used to automatically generate the program code which makes the connection.
