One or more boxes are generated for every element in a document tree after processing it under visual formatting model. A generated box has certain CSS properties associated with it and is accordingly rendered in HTML.
Following boxes are generated in CSS −
- Block-level Elements and Block Boxes
- Anonymous block boxes
- Inline-level Elements and Inline Boxes
- Anonymous inline boxes
Example
Let’s see an example of Block-level Elements and Block Boxes −
<!DOCTYPE html>

<head>
<title>CSS Block-level Elements and Block Boxes</title>
<style>
form {
width:70%;
margin: 0 auto;
text-align: center;
}
* {
padding: 2px;
box-sizing: border-box;
/*margin:5px;*/
}
input[type="button"] {
border-radius: 10px;
}
.child{
height: 40px;
width: 100%;
color: white;
border: 4px solid black;
}
.child:nth-of-type(1){
background-color: #FF8A00;
}
.child:nth-of-type(2){
background-color: #F44336;
}
.child:nth-of-type(3){
