Attributes provide additional information about HTML elements.

HTML Attributes

• All HTML elements can have attributes
• Attributes provide additional information about an element
• Attributes are always specified in the start tag
• Attributes usually come in name/value pairs like: name=”value”

The href Attribute

HTML links are defined with the <a> tag. The link address is specified in the href attribute:

Example

<a href="https://www.aaravtechcorner.com">This is a link</a>

The src Attribute

HTML images are defined with the <img> tag.

The filename of the image source is specified in the src attribute:

The width and height Attributes

Images in HTML have a set of size attributes, which specifies the width and height of the image:

Example

<img src=“img_abs.jpg” width=“500” height=“600”>

The image size is specified in pixels: width=”500″ means 500 pixels wide.

The alt Attribute

The alt attribute specifies an alternative text to be used, when an image cannot be displayed.

The value of the attribute can be read by screen readers. This way, someone “listening” to the webpage, e.g. a vision impaired person, can “hear” the element.

Example

<img src="img_abs.jpg" alt="Abs Website">

The alt attribute is also useful if the image does not exist:
