HTML Attributes
Attributes provide additional information
about HTML elements.
HTML Attributes
- HTML elements can have attributes
- Attributes provide additional information
about the element
- Attributes are always specified in the start tag
Attribute Syntax
Attributes always come in name/value pairs like this: name="value".
Examples
border="1"
href="http://www.w3scchools.com"
bgcolor="yellow"
Attributes Example 1:
<table> defines an HTML table. (You will learn more about HTML tables
later)
<table border="1">
The border attribute defines a border type for the <table> element.
Attributes Example 2:
<a> defines an anchor (an HTML link). (You will learn more about HTML
links
later)
<a href="http://www.w3schools.com">
The href attribute provides the link address for the <a> element.
Attributes Example 3:
<body> defines the body of an HTML document.
<body bgcolor="yellow">
The bgcolor attribute defines the background color for the <body>
element.
Note: bgcolor is a "dying" attribute, use styles instead (next
chapter).
Always Quote Attribute Values
Attribute values should always be enclosed in quotes. Double style quotes are the most common,
but single style quotes are also allowed.
In some rare situations, like when the attribute value itself contains
quotes, it is necessary to use single quotes:
name='John "ShotGun" Nelson'
HTML Tip - Use Lowercase Attributes
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
Newer versions of (X)HTML will demand
lowercase attributes.

WAPT
is a load, stress and performance testing tool for websites and web-based applications.
In contrast to "800-pound gorilla" load testing tools, it is designed to minimize the learning
curve and give you an ability to create a heavy load from a regular workstation.
WAPT is able to generate up to 3000 simultaneously acting virtual users using standard hardware configuration.
Virtual users in each profile are fully customizable. Basic and NTLM authentication methods are supported.
Graphs and reports are shown in real-time at different levels of detail, thus helping to manage the testing process.
