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>

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">

width and height Attributes

HTML images also have width and height 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, 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.

Example:

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

Style Attribute

The style attribute is used to specify the styling of an element, like color, font, size etc.

Example:

<p style="color:red">`This is a red paragraph.</p>

The lang Attribute

The language of the document can be declared in the <html> tag.

The language is declared with the lang attribute.

Declaring a language is important for accessibility applications (screen readers) and search engines:

<!DOCTYPE html>
<html lang="en-US">
<body>

...

</body>
</html>

The title Attribute

Here, a title attribute is added to the <p> element. The value of the title attribute will be displayed as a tooltip when you mouse over the paragraph:

Example:

<p title="I'm a tooltip">
This is a paragraph.
</p>
