Html Headings

Headings help in defining the hierarchy and the structure of the web page content.

HTML offers six levels of heading tags, 

 through ,the higher the heading level number, the greater its importance — therefore 

 tag defines the most important heading, whereas the 

 tag defines the least important heading in the document.

Importance of Headings

  • HTML headings provide valuable information by highlighting important topics and the structure of the document, so optimize them carefully to improve user engagement.
  • Don’t use headings to make your text look BIG or bold. Use them only for highlighting the heading of your document and to show the document structure.
  • Since search engines, such as Google, use headings to index the structure and content of the web pages so use them very wisely in your webpage.

These tags are mainly written inside the body tag. HTML provides us with six heading tags from

<h1> to </h6>

Every tag displays the headings in a different style and font size

Html Attributes

An attribute is used to define the characteristics of an HTML element and is placed inside the element’s opening tag. All attributes are made up of two parts − a name and a value

Name:-The name is the property you want to set. For example, the paragraph <p> element in the example carries an attribute whose name is align, which you can use to indicate the alignment of paragraph on the page.

Value:-The value is what you want the value of the property to be set and always put within quotations. The below example shows three possible values of align attribute: left, center and right.

The Id Attribute

The id attribute of an HTML tag can be used to uniquely identify any element within an HTML page. There are two primary reasons that you might want to use an id attribute on an element −

If an element carries an id attribute as a unique identifier, it is possible to identify just that element and its content.

If you have two elements of the same name within a Web page (or style sheet), you can use the id attribute to distinguish between elements that have the same name.

The title Attribute

The title attribute gives a suggested title for the element. They syntax for the title attribute is similar as explained for id attribute −

The behavior of this attribute will depend upon the element that carries it, although it is often displayed as a tooltip when cursor comes over the element or while the element is loading.

Html Element

HTML Element:-

An HTML element is defined by a starting tag. If the element contains other content, it ends with a closing tag, where the element name is preceded by a forward slash.An HTML element usually consists of a start tag and an end tag.There are some HTML elements which don’t need to be closed, such as <img…/><hr /> and <br /> elements. These are known as void elements.

Nested HTML Elements:-

HTML elements can be nested (elements can contain elements).

All HTML documents consist of nested HTML elements.

What is HTML?

HTML is the standard markup language for Web pages. HTML is easy to learn so with HTML you can create your own Website.

The Full Form of HTML is HyperText Markup Language.

  • HyperText is the method by which you move around on the web — by clicking on special text called hyperlinks which bring you to the next page. 
  • Markup is what HTML tags do to the text inside them. 
  • HTML is a Language, as it has code-words and syntax like any other language.

How does it work?

HTML consists of a series of short codes typed into a text-file by the site author — these are the tags. The text is then saved as a html file, and viewed through a browser, like Internet Explorer or Netscape Navigator. This browser reads the file and translates the text into a visible form, hopefully rendering the page as the author had intended.

Basic Syntax

When we consider a Java program, it can be defined as a collection of objects that communicate via invoking each other’s methods. Let us now briefly look into what do class, object, methods, and instance variables mean.

  • Object − Objects have states and behaviors. An object is an instance of a class.
  • Class − A class can be defined as a template/blueprint that describes the behavior/state that the object of its type supports.
  • Methods − A method is basically a behavior. A class can contain many methods. It is in methods where the logics are written, data is manipulated and all the actions are executed.
  • Instance Variables − Each object has its unique set of instance variables. An object’s state is created by the values assigned to these instance variables.

Example:

public class First

                     {

                           public static void main(String []args)

                           {

                                      System.out.println(“Hello World!!!”);

                           }

                        }

Output:

      Hello World!!!
