What is HTML?
HTML stands for Hyper Text Markup Language. It is the fundamental language for creating web pages. HTML was created by Berners Lee in 1991, but the first standard HTML specification i.e., HTML 2.0 was published in 1995.
HTML comprises of certain short codes which are called “tags”. The code of HTML is written in any text document like WordPad or notepad. This file can be saved with .html extension and viewed through a browser. The browser reads the text and converts it into a visual format.
What is XHTML?
XHTML stands for Extensible Hyper Text Markup Language. It is a variant of HTML that uses the syntax of XML. It has the same elements as in HTML, only the difference is of syntax.
What are tags, elements and attributes ?
- HTML Tags- Any document of HTML starts with heading tag. You can use various sizes of heading. Tags are used to mark-up the start and end of the HTML document. Example- < > is a start tag with no attribute.
- HTML Elements-HTML tags include opening and closing tags. The content between the tags comes under HTML elements. For example < > and > are called HTML tags. < >Hello World > This complete line is called HTML element.
- HTML attributes-Attributes contain supplementary information. An Attribute is used to define property or characteristic of an element. It is placed inside the opening tag of an element.
What is CSS?
CSS stands for Cascading Style Sheet. CSS decides how HTML elements are to be displayed on the screen. We can say that HTML makes the structure of any web page and CSS is used to decorate that page.
As the name suggests, Cascading Style Sheets, it is used to give “Styles” to the web page. CSS gives a web page a presentable look. CSS is used to construe styles of web pages, including layouts and designs.
When tags like font and color attributes were intended in HTML 3.2 specification, it creates difficulties for web developers. Developing huge websites, where fonts and colors were added to every single page is a very time taking process. To resolve this issue, W3C (World Wide Web Consortium) created CSS.
