HTML Attributes

  • All HTML elements can have attributes
  • Attributes provide additional information about an element

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

<img src="img_girl.png">

The width and height Attributes

HTML images also have width and height attributes, which specifies the width and height of the image:

The alt Attribute

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

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

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

The HTML Style Attribute

Setting the style of an HTML element, can be done with the style attribute.

The HTML style attribute has the following syntax:

The property is a CSS property. The value is a CSS value.
