ValueDescription
some valueSpecifies the value of the attribute (as a string)

Older browsers support

Data attributes were introduced in HTML5 which is supported by all modern browsers, but older browsers before HTML5 don’t recognize the data attributes.

However, in HTML specifications, attributes that are not recognized by the browser must be left alone and the browser will simply ignore them when rendering the page.

Web developers have utilized this fact to create non-standard attributes which are any attributes not part of the HTML specifications. For example, the value attribute in the line bellow is considered a non-standard attribute because of the specifications for the <img> tag don’t have a value attribute and it is not a global attribute:

<img src="sample.jpg" value="test" />

href

Specifies the destination address. It can be an absolute or relative URL or the name of an anchor. An absolute URL is the complete URL of a website like http://example.com/. A relative computer address points to a different directory and/or document within the constant web site, e.g. /about-us/ points to the directory “about-us” inside the root directory (/). When pointing to another directory without explicitly specifying the document, web servers typically return the document “index.html” inside that directory.
