CSS Properties

CSS `background` Property – Syntax & Examples

The background property in CSS is used to set the background styles of an element, including color, image, position, size, and more.

1. Basic Syntax

selector {
    background: value;
}

You can also use individual background properties:

selector {
    background-color: value;
    background-image: url('image.jpg');
    background-repeat: repeat | no-repeat;
    background-position: top | center | bottom left;
    background-size: cover | contain;
    background-attachment: fixed | scroll;
}

2. Examples

Example 1: Setting a Solid Background Color

body {
    background-color: lightblue;
}

This sets the background color of the entire page to light blue.

Example 2: Adding a Background Image

body {
    background-image: url('background.jpg');
    background-repeat: no-repeat;
    background-size: cover;
}

background-image: Sets an image as the background.
background-repeat: no-repeat: Prevents the image from repeating.
background-size: cover: Ensures the image covers the full area.

Example 3: Fixed Background Image

body {
    background-image: url('background.jpg');
    background-attachment: fixed;
    background-size: cover;
}

background-attachment: fixed; keeps the image fixed when scrolling.

Example 4: Using Shorthand Background Property

body {
    background: lightblue url('background.jpg') no-repeat center/cover fixed;
}

This is equivalent to:

body {
    background-color: lightblue;
    background-image: url('background.jpg');
    background-repeat: no-repeat;
    background-position: center;
    background-size: cover;
    background-attachment: fixed;
}

Conclusion

The background property in CSS helps style elements with colors, images, and positioning. Learning how to use it properly can make your web design visually appealing! 🚀

Padding in CSS

Padding is a CSS property that adds space inside an element, between its content and its border. It helps in controlling the spacing inside elements without affecting their border or margin.

Syntax:

element {
    padding: value;  /* Can be in px, %, em, etc. */
}

Different Ways to Use Padding:

Equal Padding on All Sides

div {
    padding: 20px;  /* Adds 20px padding on top, right, bottom, and left */
}

Different Padding for Each Side

div {
    padding-top: 10px;
    padding-right: 20px;
    padding-bottom: 15px;
    padding-left: 25px;
}

Shorthand Notation
```
div {
    padding: 10px 20px 15px 25px;
    /* Order: TOP RIGHT BOTTOM LEFT */
}
```
- Two values: padding: 10px 20px; (Top-Bottom 10px, Left-Right 20px)
- Three values: padding: 10px 20px 15px; (Top 10px, Left-Right 20px, Bottom 15px)
- One value: padding: 10px; (Applies 10px padding on all sides)

Example:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>CSS Padding Example</title>
    <style>
        .box {
            background-color: lightblue;
            padding: 20px; /* Adds space inside the box */
            border: 2px solid blue;
            width: 200px;
            text-align: center;
        }
    </style>
</head>
<body>
    <div class="box">This is a padded box</div>
</body>
</html>

Key Points:

Padding increases the inner space of an element.
It does not affect the margin (space outside the element).
It can be set in various units like px, %, em, rem, etc.
Negative padding values are not allowed.
