Chapter 12. CSS: Styling Backgrounds

In this chapter, we will explore how to style backgrounds in CSS. Backgrounds play a crucial role in the design and visual appeal of a web page. You will learn how to apply different background styles such as color, images, and patterns, and how to control the positioning, repetition, and attachment of background images.
The following topics are covered in this chapter:
background-color
In this section, we’ll explore the background-color
property, which is used to set the background color of an element. This property can accept various values, including color names, hex codes, RGB, or RGBA. For example, you can set the background color of a webpage or a specific element like this: background-color: #f0f0f0;
.
background-image
In this section, we'll cover the background-image
property, which allows you to set an image as the background of an element. The image is specified using a URL, and it will repeat by default unless specified otherwise. The syntax for using this property looks like: background-image: url('image.jpg');
.
background-size
In this section, we’ll examine the background-size
property, which controls the size of the background image. You can set the size in pixels, percentages, or use keywords like cover
or contain
to ensure the image scales proportionally within the container. For example: background-size: cover;
ensures the image covers the entire background area.
background-repeat
In this section, we’ll discuss the background-repeat
property, which determines whether the background image repeats. By default, the image repeats both horizontally and vertically. You can control the repetition using values like repeat
, no-repeat
, repeat-x
, or repeat-y
. For instance, using background-repeat: no-repeat;
ensures that the image will only appear once.
background-position
In this section, we’ll cover the background-position
property, which allows you to set the position of the background image within an element. This can be done using specific values such as top left
, center center
, or pixel-based values. For example, background-position: center;
will center the image within the element.
background-attachment
In this section, we’ll explore the background-attachment
property, which controls whether the background image scrolls with the page or stays fixed. The default setting is scroll
, but you can change it to fixed
to keep the background image in place while the rest of the page content scrolls. For example: background-attachment: fixed;
ensures the background image remains stationary during page scrolling.
background (Multiple Properties)
In this section, we'll examine the background
shorthand property, which allows you to define multiple background-related properties in a single line. This includes background-color
, background-image
, background-size
, background-repeat
, background-position
, and background-attachment
. This shorthand can simplify your CSS code, making it more concise and easier to maintain.
