Attributes provide additional information about HTML elements.
- HTML elements can have attributes
- Attributes provide additional information about an element
- Attributes are always specified in the start tag
- Attributes come in name/value pairs like: name="value"
lang Attribute
The document language can be declared in the <html> tag.
The language is declared in the lang attribute.
Declaring a language is important for accessibility applications (screen readers)
and search engines.
Ex :
<!DOCTYPE html>
<html lang="en-US">
<body>
<h1>My First Heading</h1>
<p>My first paragraph.</p>
</body>
</html>
<html lang="en-US">
<body>
<h1>My First Heading</h1>
<p>My first paragraph.</p>
</body>
</html>
title Attribute
HTML paragraphs are defined with the <p> tag.
In this example, the <p> element has a title attribute. The value of the attribute is "About Weblbox".
Ex :
<p title="About Weblbox">
Weblbox is a web developer's site.It provides tutorials and references covering
many aspects of web programming,
including HTML, CSS, JavaScript, XML, SQL, PHP, ASP, etc.
</p>
" When you move the mouse over the element, the title will be displayed as a tooltip. "
href Attribute
HTML links are defined with the <a> tag. The link address is specified in
the href attribute.
Size Attributes
HTML images are defined with the <img> tag.
The filename of the source (src), and the size of the image (width and height) are all provided as attributes.
Ex :
<img src="Weblbox.jpg" width="104" height="142">
alt Attribute
The alt attribute specifies an alternative text to be used, when an HTML element cannot be displayed.
The value of the attribute can be read by "screen readers". This way, someone "listening" to the webpage, i.e. a blind person, can "hear" the element.
Ex :
<img src="Weblbox.jpg" alt="Weblbox.com" width="104" height="142">
" Lower case is the most common. Lower case is easier to type.
At Weblbox we always use lower case attribute names. "
At Weblbox we always use lower case attribute names. "
