Html is simply the acronym for hypertext markup language.It displays data while xml describes data.With html you can create your own website.It teaches you to create simple web pages using HTML tags and HTML formatting features. It also teaches you to link web pages using hypertext links, hypermedia links and image maps.It can be described as a set of special codes referred to as "tags," which instruct a web browser how to display a hypertext document. Think of it is as a collection of styles (indicated by markup tags) that define the various components of a web page. All html documents are written in plain text (ASCII) format, making them universally readable by different web browsers running on different computer operating systems. HTML tags consist of a left angle bracket (< or "less than" symbol) followed by the name of the tag and closed by a right angle bracket (> or "greater than" symbol). Some HTML tags, like the ones used to indicate a new paragraph or a line break
, stand alone. Most tags however, are paired, with a beginning (or open) and an ending (or close) tag. The ending tags are the same as the beginning tags except that they are preceded by a forward slash (/).
These days, it is completely unnecessary to know HTML in order to create web documents. Word processing programs like Microsoft Word can automatically convert your text documents into HTML.However,all you need is a text editor like Notepad and a web browser.
Technology has enhanced communication to great levels. Today information can be conveyed across vast distances within seconds. This has been made possible by the World Wide Web(WWW). The WWW or Web is a collection of computers all over the world, which communicate with each other using a communication protocol called HTTP.
HTML comprises two major parts which includes a "head" and a "body".
The "head" contains the title of the document, and the heading - which is the heading of that particular page in the document while the body contains the entire content of the document.
The "head" is not directly visible, but it can have a tremendous impact on how your page looks. In a nutshell, the head section of an html page is the area between the
tags. Here are a few items which most head sections will possess while the html code in the "body" directly affects what your visitors see. If you post an image or specific line of text, the change is immediate and obvious.
Most webmasters use Cascading Style Sheets, or CSS, to format their sites. You can link to an external style sheet in your page header and the page will apply that style sheet's rules. This can be a tremendous time-saver in the long run, since you can put all your formatting rules in one document. If you need to change a rule later, you can do so in one place instead of having to go through every page.
You can also link to other types of external pages, such as Javascript programs. Again, this allows you to call on one document from several different pages, saving you a great deal of time (and, incidentally, reducing bandwidth demands as well).
Page title – You can define your page's title in the head section and this title will show up in the top bar of your visitors' browsers when they view the page. To define a title, you enter a line into the head as follows:
Nigeria is a good country
This title will also determine the linked text when your page shows up in a list of search results, so a good title can really help with search engine optimization.
