Html Attributes
We have seen few HTML tags and their usage like heading tags <h1>, <h2>, paragraph tag
<p> and other tags. We used them so far in their simplest form, but most of the HTML tags
can also have attributes, which are extra bits of information.
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:
v 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.
v 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.
Attribute names and attribute values are case-insensitive. However, the World Wide Web
Consortium (W3C) recommends lowercase attributes/attribute values in their HTML 4
recommendation

<!DOCTYPE
html> <html>
<head>
<title>Align
Attribute Example</title> </head>
<body>
<p
align="left">This is left line</p> <p
align="center">This is center aligned</p> <p
align="right">This is right line</p> </body>
</html> |
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.
We will
discuss style sheet in separate tutorial. For now, let's use the id attribute to
distinguish between two paragraph elements as shown below.
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
Example :
|
<!DOCTYPE
html> <html>
<head>
<title>The title Attribute
Example</title> </head>
<body>
<h4
title="Hello HTML!">Titled Heading</h4> </body>
</html> |
The Class Attribute
The class
attribute is used to associate an element with a style sheet, and specifies the
class of element. You will learn more about the use of the class attribute when
you will learn Cascading Style Sheet (CSS). So for now you can avoid it.

The Style Attribute
Styles in HTML are basically rules
that describe how a document will be presented in a browser. Style information
can be either attached as a separate document or embedded in the HTML document.
There are 3 ways of implementing
style in HTML :
1. Inline Style : In this method, the style attribute is used inside
the HTML start tag.
2. Embedded Style :
In this method, the style element is used inside the <head> element of
the document.
3. External Style Sheet :
In this method the <link> element is used to point to an external CSS
file.
