In the HTML API there are many tags or elements that are rarely used because they have very specific functions and therefore are not as famous but are still useful; today we will look at a couple of HTML tags that you may not know:
The element <base>
This element defines a URL and/or global target for the document that allows overwriting the target and/or href attributes that are not specified in an <a> element.
IMPORTANT! There can only be one <base> element in the document head:
If we have the following HTML code:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Elemento base 1</title>
<base href="https://www.bing.com/" target="_blank">
</head>
<body>
<a href="">Google.com</a>
</body>
</html>
We will see that by clicking on the "Google.com" link it will redirect us to the Microsoft search engine at the following address: https://www.bing.com/.
If, on the other hand, we specify the URL in the href attribute of the link:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Elemento base 2</title>
<base href="https://www.bing.com/" target="_blank">
</head>
<body>
<a href="http://www.google.com/">Google.com</a>
</body>
</html>
The link will redirect us to Google.com, although not specifying the target will open the link in a new tab.
The element <abbr>
This element simply allows you to define an abbreviation as we can see in the following example:
<p>El lenguaje de programación <abbr title="PHP Hypertext Pre-processor">PHP</abbr>...</p>
El lenguaje de programación PHP...
