HTML Attributes

Attributes are additional information provided by HTML elements, such as width, height, style, etc.

HTML Attributes

• HTML elements can set attributes

• Attributes can add additional information to the element

• Attributes are generally described in the start tag

• Attributes are always named/appear in the form of value pairs, such as: target="_blank".

Attribute example

HTML hyperlinks are defined by the <a> tag, and the address of the hyperlink is specified in the href attribute:

<a href="https://www.oldtoolbag.com">This is a hyperlink</a>

Commonly used HTML attribute values

Attribute values should always be enclosed in quotes.

Double quotes are the most commonly used, but it is also fine to use single quotes.

Tip: In some individual cases, such as attribute values themselves containing double quotes, then you must use single quotes, for example: name='John "ShotGun" Nelson&39;

HTML Tip: Use lowercase attributes

Attributes and attribute values are case-insensitive.

However, the World Wide Web Consortium in its HTML 4 Recommended in the standard recommendations for lowercase attributes/Attribute values.

While the new version of (X)HTML requires the use of lowercase attributes.

Suggestion: Use lowercase tags consistently
