color: red;
}

margin

Margin is used to add space outside an element, and padding is used to add space inside an element. The margin property is used to add space around the outside of an element. It can be set for each side of the element individually (top, right, bottom, left) or all sides at once.
For example, to add 20 pixels of margin to the top and bottom of an element, you can use the following CSS:

element {
margin-top: 20px;
margin-bottom: 20px;
}

To add 20 pixels of margin to all sides of an element, you can use the following CSS:

element {
margin: 20px;
}

</div>
</body>
</html>

padding

The padding property in CSS is used to add space within an element. It can add space inside an element's top, bottom, left, and right sides. Padding is different from margins, which add space outside of an element.
It is also applied similarly to how margin is:

element {
padding: 10px; /* Adds 10 pixels of padding to all sides of the element */
}

Just like margin, padding can also be specified different values for each side of the element:

element {
padding-top: 5px; /* Adds 5 pixels of padding to the top of the element */
padding-right: 10px; /* Adds 10 pixels of padding to the right side of the element */
padding-bottom: 15px; /* Adds 15 pixels of padding to the bottom of the element */
padding-left: 20px; /* Adds 20 pixels of padding to the left side of the element */
}
