When comparing the CSS class with the ID, the difference is that the CSS class applies styling to multiple elements. ID, on the other hand, applies a style to a single element. The ID is also special that you can use a special URL to link directly to an element and it is used by JavaScript.

CSS , selectors are used to target a specific element or multiple elements on a web page. Once an element has been targeted, a style or a set of styles can be applied to the element.

A wide variety of selectors are available. Two of the most commonly used are and ID. Both are used to target items with the title.

and ID selectors

What is the difference between tags > and ID ? This is a question asked by many developers who are new to CSS and we’ll answer in this guide.

 By the time you finish reading this guide, you will know the differences between these two selectors. You will have the information you need to make an informed decision on which selection to use in your code. Let’s get started. 
    CSS selectors  
 a web page , you want to apply certain styles to specific elements of the page. For example, you can set the text color of all 
tags to green or change the header font size . 
 Selectors allow you to target specific elements on a web page to which you can apply styles. There are a lot of selectors available in CSS, such as universal selectors, descendant selectors, child selectors, and grouping selectors . If you want to learn more about CSS selectors, read our beginner’s guide to   CSS selectors.

 Two selectors,  and id , are used for style elements based on the class and ID assigned to an HTML element, respectively, but these selectors are often confusing, so we’ll explore what each does.

    the id selector is unique  
the id selector allows you to define style rules applicable to a  single element  on the web page. Each web page can have only one element with a single  ID attribute. This means that the ID picker can never be used to style more than one element. 
 ID selectors are defined using a pound sign. They are immediately followed by the identity value to which you want to apply a set of style rules. Here is an example of the identity selector in action: 
 This style applies to the 
element in our HTML document with the id betaBanner. The style will set the element’s background color to orange and the text color in the element white. 
    The class selector is not unique  
a class selector allows you to define style rules that apply to  any element  with a class attribute equal to a certain value. 
 As mentioned - above, the identity selector can not be used for an element style. in fact, ID can only be used once on a Web page. the Courses, on the other hand, can be used on multiple elements. So if you apply a style using a class selector, any element that shares that class will be subject to the styles you define.
 Class selectors are defined using a period, followed by the value of the class to which you want to apply a set of styles. Here is an example of the class selector in action:
 .  .orangeBackground {background-color: orange; }

 This style sets the background color of our 
tag to orange. Also, the style defines the background color of our orange tag, we could do it using this code:

 In this code, all styles rules defined for orangeBackground and large classes are applied to our web element. With an ID card , however, we could not reproduce this behavior, because each item can only have one ID. 
    IDs have a unique browser function  
So far we’ve discussed that IDs can apply styles to a single element. Unlike classes which can apply styles to multiple elements. This is not the only difference between class and ID selectors.
 In the browser, classes have no special function. Their main purpose is to allow you to apply styles to a number of elements on a web page. ID, on the other hand, can be used by the browser to access a certain part of the web page. 
 If you assign an ID to an element, you can use a special URL to link directly to that element. This behavior works because IDs are unique on a web page. 
 Suppose we want to send a link to our website that automatically scrolls to the user with a header. We could do it using this code: 
 In this code, we have assigned an identity card to the tag  tag which contains the text Three. Now we could send a user a direct scrolling link to that element on the web page. This is done using the following address:
