Sometimes a website designer wishes to display graphics or text from another location on a Web page. The external material is usually found on another page. The designer can create a frame with frameset tags, and program in the location of the other page. Alternatively, he can use the iframe tag to display a frame and again program in the location of the other material. In either case, the graphics and/or text from the other page appear in the frame situated on the designer's new Web page.
XHTML validation works for developers as a debugging tool and future-proof quality check; helps ease maintenance; and teaches good practices, according to the World Wide Web Consortium, or W3C. Producing 100 percent-compliant XHTML is sometimes an unattainable goal, especially when you must include HTML code snippets from other websites, such as those for traffic counters or Facebook feature integration. If a client requires XHTML validation -- or if you want to get nonstandard or invalid XHTML to pass through a validation service for your personal satisfaction -- you'll find techniques to help.
HTML (Hypertext Markup Language) and XHTML (more streamlined version of HTML) are facets of website programming. By understanding HTML and XHTML, you can create simple websites. Furthermore, knowledge of HTML is still necessary when working with more complex website programming environments, as the positioning of certain page elements and styles depends on this markup language. After you understand basic HTML/XHTML syntax, you will be able to expand on this information using a number of references.
XHTML, or Extensible Hypertext Markup Language is a combination of HTML, Hypertext Markup Language and XML, Extensible Markup Language, resulting in a cleaner version of HTML that is almost identical to HTML 4.01. XHTML is recommended for website design because it consists of well-formed code that is compatible in all web browsers. The best way to get started with XHTML is to learn the basics of the markup language, then begin experimenting with it.
At first glance, HTML and XHTML look very similar. XHTML stands for EXtensible HyperText Markup Language and is a stricter version of HTML, with greater requirements when it comes to the layout and appearance of the code used to build Web pages. To convert to XHTML, you must close all elements, use lowercase and nest elements properly. Converting your website is not difficult -- it just may take some time, depending on how many pages exist on your site. XHTML files use the .html file extension, so when converting, you do not need to change any file names.
When you create a website, you can choose from a variety of programming and coding languages or technologies. It is likely that you will incorporate multiple coding styles into your project to achieve the desired effect. For example, while Hypertext Markup Language (HTML) has been the backbone of Web pages since the advent of the Internet, you may also use PHP: Hypertext Preprocessor (PHP) code to add scripts to your applications or cascading style sheets (CSS) to add style effects to your pages.

In order to define a citation in HTML, you'll need to use little instructions called "tags" around the text you want to alter. Citations in HTML are designed to mark text that is being quoted from print or from dialogue. Typically, browsers render text enclosed in citation tags as italic.
Though links to other web pages are most often accomplished through hyperlinked text, occasionally designers prefer to define familiar looking push buttons to take their users to different locations.
Anchors are used to create links to other documents, the essential activity of the World Wide Web. They can also be used to define bookmarks within the current document, so that other hyperlinks can link to them.
Adding an input field to your web page allows you to capture information from the user. The user input can be retrieved and used via script, or sent back to the server as part of a form submission. Input fields are specified with the INPUT HTML tag.
Scripting is a powerful means to add functionality to your web pages, even to the point of turning them into full-fledged applications in their own right. Scripts are placed on web pages using the SCRIPT tag.
As a way of making things easier on the web master and thus preventing the need to repeatedly type the same HTML code over and over, HTML's Style syntax allows you to enter HTML code once and have the browser repeat that code in the necessary places.
HTML permits non-standard objects to be added to web pages, using the EMBED element. A common use of embedding is to add music clips that play when a page is loaded.
