HTML Attributes

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.w3schools.com">This is a link</a>

You will learn more about links and the <a> tag later in this tutorial.

---

The src Attribute

HTML images are defined with the <img> tag.

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

Example

<img src="img_girl.jpg">

he 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_girl.jpg" width="500" height="600">

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 blind person, can "hear" the element.

Example

<img src="img_girl.jpg" alt="Girl with a jacket">

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

Example

See what happens if we try to display an image that does not exist:

<img src="img_typo.jpg" alt="Girl with a jacket">
