(10) CSS (Padding)
Padding - Individual Sides
CSS has properties for specifying the padding for each side of an element: padding-top padding-right padding-bottom padding-left All the padding properties can have the following values: length - specifies a padding in px, pt, cm, etc. % - specifies a padding in % of the width of the containing element inherit - specifies that the padding should be inherited from the parent element Note: Negative values are not allowed. Example Set different padding for all four sides of a <div> element: div { padding-top: 50px; padding-right: 30px; padding-bottom: 50px; padding-left: 80px; }
CSS Padding Properties
Property Description padding A shorthand property for setting all the padding properties in one declaration padding-bottom Sets the bottom padding of an element padding-left Sets the left padding of an element padding-right Sets the right padding of an element padding-top Sets the top padding of an element
CSS Padding
The CSS padding properties are used to generate space around an element's content, inside of any defined borders. With CSS, you have full control over the padding. There are properties for setting the padding for each side of an element (top, right, bottom, and left).
Padding and Element Width
The CSS width property specifies the width of the element's content area. The content area is the portion inside the padding, border, and margin of an element (the box model). So, if an element has a specified width, the padding added to that element will be added to the total width of the element. This is often an undesirable result. Example Here, the <div> element is given a width of 300px. However, the actual width of the <div> element will be 350px (300px + 25px of left padding + 25px of right padding): div { width: 300px; padding: 25px; } To keep the width at 300px, no matter the amount of padding, you can use the box-sizing property. This causes the element to maintain its width; if you increase the padding, the available content space will decrease. Example Use the box-sizing property to keep the width at 300px, no matter the amount of padding: div { width: 300px; padding: 25px; box-sizing: border-box; }
Padding - Shorthand Property
To shorten the code, it is possible to specify all the padding properties in one property. The padding property is a shorthand property for the following individual padding properties: padding-top padding-right padding-bottom padding-left So, here is how it works: If the padding property has four values: padding: 25px 50px 75px 100px; top padding is 25px right padding is 50px bottom padding is 75px left padding is 100px Example Use the padding shorthand property with four values: div { padding: 25px 50px 75px 100px; } If the padding property has three values: padding: 25px 50px 75px; top padding is 25px right and left paddings are 50px bottom padding is 75px Example Use the padding shorthand property with three values: div { padding: 25px 50px 75px; } If the padding property has two values: padding: 25px 50px; top and bottom paddings are 25px right and left paddings are 50px Example Use the padding shorthand property with two values: div { padding: 25px 50px; } If the padding property has one value: padding: 25px; all four paddings are 25px Example Use the padding shorthand property with one value: div { padding: 25px; }
