CSS Backgrounds

In CSS, background properties are used to set the background color, background image, background-repeat, etc of an HTML element. Followings are a few background CSS properties:

• background-color
• background-image
• background-repeat
• background-position
• background (Shorthand property)

CSS Background Color

You can set the background color of an HTML element using background-color property of CSS. As you have seen already in the CSS Colors section.

CSS Background Image

You can set the background image of an HTML element using background-image property. You should have an image file to use this property. The value of the background-image property will be a url( ), which takes the path of an image file.

For example:

body{
     background-image:url("wallpaper.png");
 }

By default, the background-image property repeats an image both horizontally and vertically. If you want to modify it, then by using background-repeat property it can be modified.

The values for this are no-repeat, repeat-x, repeat-y, etc. For example:

body{
     background-image:url("wallpaper.png");
     background-repeat:no-repeat;
 }
div{
     background-image:url("wallpaper2.png");
     background-repeat: repeat-x;
}

CSS Background (Shorthand property)

The background property is a shorthand property used to specify the multiple values in a single line to background property.

For example:

body{
     background-color:#ffffff;
     background-image:url("wallpaper.png");
     background-repeat:no-repeat;
 }

/* These property can be defined with shorthand like this */

body{
     background:#fffff url("wallpaper.png") no-repeat;
}

CSS Height & Width

The height and width properties are used to set the height and width of an element.

The height and width properties do not include padding, borders, or margins. It sets the height/width of the area inside the padding, border, and margin of the element.

The value for the height and width properties are the following:

div.square{
    height:200px;
    width:200px;
    background-color:pink;
}
div.rectangle{
    height:200px;
    width:400px;
    background-color:green;
}
div.percentsize{
    height:200px;
    width:50%;
    background-color:rgb(255,255,0);
}

    height:auto;
    width:auto;
    background-color:#00f;
}

CSS Margins & Padding

The CSS margin properties are used to create space around elements, outside of any defined borders. Whereas the CSS padding properties are used to generate space around an element’s content, inside of any defined borders.

The value for the margin and padding properties are the following:

NOTE: Negative values are allowed for margin but not allowed for padding.

Individual Sides

There are properties for setting the margin for each side of an element (top, right, bottom, and left).

• margin-right
• margin-bottom
• margin-left

Similarly, there are properties for setting the padding for each side of an element.

• padding-top
• padding-right

	padding-top:25px;
	padding-right:25px;
	padding-bottom:25px;
	padding-left:25px;
	border:1px solid green;
}

Shorthand Property

To shorten the code, it is possible to specify all the margin/padding properties in one property.

The value for the margin and padding property can have one value, two values, three values, or four values.

/* four values (top=30px, right=20px, bottom=40px, left=50px) */
p{
    margin: 30px 20px 40px 50px;
}

/* three values (top=30px, right=40px, bottom=50px, left=40px) */
p{
    margin: 30px 40px 50px;
}

/* two values (top and bottom=30px, left and right=20px) */
p{

Some examples of rounded borders

CSS Box Model

In CSS, each element in an HTML page is represented as a box model. The box model represents margins, borders, padding, and the actual content as you can see in the below image:

div {
  width: 400px;
  border: 20px solid lightblue;
  padding: 50px;
  margin: 20px;
}

Height & Width Calculation

Here, we have defined the size of the <div> element with the following CSS properties:

div{
   height:100px;
   width:300px;
   margin:20px;
   padding:10px;
   border:20px solid #4366f2;
}

Total width = 400px which is calculated as follows:

Width of the element + left margin + right margin + left padding + right padding + left border + right border

300px + 20px + 20px + 10px + 10px + 20px + 20px = 400px

Total height = 200px which is calculated as follows:

Height of the element + top margin + bottom margin + top padding + bottom padding + top border + bottom border

100px + 20px + 20px + 10px + 10px + 20px + 20px = 200px
