In this article we are going to explore common attributes in HTML and how to use them correctly. If you are learning to program in HTML, it is essential to understand attributes and how they affect the structure and functionality of a web page.
What is an attribute in HTML?
To begin, we need to understand what exactly an attribute is in HTML. An attribute is a characteristic or property that is added to an HTML tag to provide it with more information or to change its behavior.
Attributes are used to customize and control how an HTML element displays and behaves. They can be added to any HTML tag and are specified within the opening tag in the format key="value". For example:
<a href="https://nelkodev.com/en/">Visit Nelkodev</a>
In this example, the "href" attribute is used to specify the URL to which the link should be directed.
Examples of common attributes
Next, we will look at some examples of common attributes in HTML:
href attribute
The "href" attribute is used to specify the URL to which a link should point. For example:
<a href="https://nelkodev.com/en/">Visit Nelkodev</a>
id attribute
The "id" attribute is used to uniquely identify an HTML element. It can be useful for applying styles or accessing that element with JavaScript. For example:
<div id="mi_elemento">Item content</div>
class attribute
The "class" attribute is used to assign one or more CSS classes to an HTML element. It can be useful to apply specific styles to that element. For example:

HTML comments will not be displayed in the browser and will not affect the display of the web page.

Remember that attributes are specified within HTML tags and are made up of a name and a value. Additionally, comments can also be added to the HTML code to clarify its operation.
