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.

Some people don't realize a CSS class is used for styling more than one HTML element in your page, a CSS id can be placed on only one HTML element in your page otherwise it will be marked as invalid by w3 validator many people make this mistake

Valid:

<style type="text/css">
.class
{
   color: #222;
}
</style>
<span class="class">first element</span>
<span class="class">second element</span>
 

InValid:

<style type="text/css">
#id
{
   color: #222;
}
</style>
<span id="id">first element</span>
<span id="id">second element</span>

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>
