The Box model consists of margins, borders, padding and content.

Content

this is the place where texts and images appear in the box.

Padding

It adds space around the content and it is transparent. and we can say that padding is an area created inside an element.

Border

It is that border around the content and padding.

Margin

It adds the area outside the border, and it is also transparent

div{
    height: 150px;
    width: 150px;
    border: 1px solid red;
    margin: 100px 100px;
    padding: 10px 10px;
}

Output:

Initially, I created a box using height and width, and then I gave 1px of the border with the color of red, then I used margin property with the top and bottom, right and left specifications it adds the margin from outside, then I did padding inside the box with top and bottom, right and left of 10 px.
