HTML with Classes

HTML classes are used to define a set of elements with common characteristics and apply a specific style or behavior to them using CSS. HTML classes are defined using the class attribute and can be assigned to any HTML element.

In below example, we have assigned classes to several HTML elements, such as the header, nav, and section elements. These classes are defined in the CSS code and can be used to apply specific styles to these elements.

For example, the .main-header class sets the background color, font color, padding, and text alignment of the header element. The .nav-link class sets the font color and text decoration of the a elements inside the nav element.

Using HTML classes allows developers to apply consistent styles and behaviors across multiple elements on the web page. It also makes it easier to maintain and update the CSS code, as changes can be applied to all elements with a specific class at once.
