HTML Attributes
HTML attributes are additional pieces of information that can be added to HTML elements to provide extra details or settings about those elements. Attributes are always specified in the opening tag of an HTML element and are written as name-value pairs.
Here’s a breakdown of HTML attributes:
Name: The name of the attribute, which identifies the specific property or characteristic being set. Attributes are usually lowercase, but they are not case-sensitive.
Value: The value assigned to the attribute, enclosed in double quotes. The value provides information or settings for the attribute.
Here’s an example of an HTML element with attributes:
<a href="https://www.example.com" title="Visit Example">Click here</a>
In this example:
<a>is the HTML element (an anchor/link).hrefis an attribute that specifies the URL the link points to (https://www.example.com).titleis another attribute that provides additional information (a tooltip) when you hover over the link (Visit Example)."Click here"is the content between the opening and closing tags, which is the visible text for the link.
