Border - Shorthand property

As you can see from the examples above, there are many properties to consider when dealing with borders.

To shorten the code, it is also possible to specify all the individual border properties in one property. This is called a shorthand property.

The border property is a shorthand for the following individual border properties:

• border-width
• border-style (required)
• border-color

Example

border:5px solid red;

All CSS Border Properties

CSS Outlines

An outline is a line that is drawn around elements (outside the borders) to make the element "stand out".

The outline properties specify the style, color, and width of an outline.

Examples

This example demonstrates how to draw a line around an element, outside the border edge.

Set the style of an outline

This example demonstrates how to set the style of an outline.

Set the color of an outline

This example demonstrates how to set the color of an outline.

Set the width of an outline

This example demonstrates how to set the width of an outline.

CSS Outline

An outline is a line that is drawn around elements (outside the borders) to make the element "stand out".

However, the outline property is different from the border property.

The outline is not a part of an element's dimensions; the element's total width and height is not affected by the width of the outline.

All CSS Outline Properties

The number in the "CSS" column indicates in which CSS version the property is defined (CSS1 or CSS2).

CSS Margin

The CSS margin properties define the space around elements.

Margin

The margin clears an area around an element (outside the border). The margin does not have a background color, and is completely transparent.

The top, right, bottom, and left margin can be changed independently using separate properties. A shorthand margin property can also be used, to change all margins at once.

Possible Values

It is possible to use negative values, to overlap content.

Margin - Individual sides

In CSS, it is possible to specify different margins for different sides:

Example

margin-top:100px;

margin-bottom:100px;

margin-right:50px;

margin-left:50px;

Margin - Shorthand property

To shorten the code, it is possible to specify all the margin properties in one property. This is called a shorthand property.

The shorthand property for all the margin properties is "margin":

Example

margin:100px 50px;

The margin property can have from one to four values.

• margin:25px 50px 75px 100px;
  • top margin is 25px
  • right margin is 50px
  • bottom margin is 75px
  • left margin is 100px
• margin:25px 50px 75px;
  • top margin is 25px
  • right and left margins are 50px
  • bottom margin is 75px
• margin:25px 50px;
  • top and bottom margins are 25px
  • right and left margins are 50px
• margin:25px;
  • all four margins are 25px

All CSS Margin Properties

CSS Padding

The CSS padding properties define the space between the element border and the element content.

Padding

The padding clears an area around the content (inside the border) of an element. The padding is affected by the background color of the element.

The top, right, bottom, and left padding can be changed independently using separate properties. A shorthand padding property can also be used, to change all paddings at once.

Possible Values

Description

Defines a fixed padding (in pixels, pt, em, etc.)

Defines a padding in % of the containing element

Padding - Individual sides

In CSS, it is possible to specify different padding for different sides:

Example

padding-top:25px;

padding-bottom:25px;

padding-right:50px;

padding-left:50px;

Padding - Shorthand property

To shorten the code, it is possible to specify all the padding properties in one property. This is called a shorthand property.

The shorthand property for all the padding properties is "padding":

Example

padding:25px 50px;

The padding property can have from one to four values.

• padding:25px 50px 75px 100px;
  • top padding is 25px
  • right padding is 50px
  • bottom padding is 75px
  • left padding is 100px
• padding:25px 50px 75px;
  • top padding is 25px
  • right and left paddings are 50px
  • bottom padding is 75px
• padding:25px 50px;
  • top and bottom paddings are 25px
  • right and left paddings are 50px
• padding:25px;
  • all four paddings are 25px
