    A class is essentially an object.

    .class {

    }


    That would result in nothing, but if you were to add a background-color or anything, then that object will turn into something useful for your website. That being said - classes do not have to contain any visual aspects. They can be used to wrap other classes to ensure everything fits nicely together when resizing your screen.

    Class is used when we want to write properties like text align, color width etc.

    In the CSS, a class selector is a name preceded by a full stop (“.”). You can also define your own selectors in the form of class.
    .class1 {
    color: red;
    font-weight: bold;
    }
    The HTML refers to the CSS by using the attributes class
    <p class="class1">This is class1 selector of class attribute in Paragraph tag</p>
